Re: Exception accessing T5 Registry from other servlet

2009-12-07T15:11:36Z

Found something that seems to work by reading carefully through
TapestryModule.java, see code below. To me, it seems strange that I have to
do this. Do any of you guys see anything wrong with this?

  public void
contributeHttpServletRequestHandler(OrderedConfiguration
configuration, @Inject @Symbol(SymbolConstants.CHARSET) final String
applicationCharset, @Primary final SessionPersistedObjectAnalyzer analyzer,
final RequestGlobals requestGlobals) {

    HttpServletRequestFilter storeRequestResponse = new
HttpServletRequestFilter() {

      public boolean service(HttpServletRequest servletRequest,
HttpServletResponse servletResponse, HttpServletRequestHandler handler)
throws IOException {
        Request request = new RequestImpl(servletRequest,
applicationCharset, analyzer);
        Response response = new ResponseImpl(servletResponse);
        requestGlobals.storeRequestResponse(request, response);
        return handler.service(servletRequest, servletResponse);
      }
    };

    configuration.add("StoreRequestResponse", storeRequestResponse,
"before:*");
  }

Re: Exception accessing T5 Registry from other servlet

2009-12-07T13:35:05Z

Thanks!

Didn't work though. Tried running requestGlobals.storeServletRequestResponse
before asm.get(...), still same error because requestGlobals.getRequest() is
still null after storing httprequest.

I discovered that requestGlobals.getHTTPServletRequest() returns a live and
working request, while requestGlobals.getRequest() returns null. I also put
a breakpoint in TapestryModule "StoreIntoGlobals", and it is run before my
code.

So, the Request and Response properties of requestGlobals aren't populated
when using the Registry from another servlet i think. Am I right? Is there
any way to make this work?

It looks like the Request wasnt. Try getting the RequestGlobals service  
and invoking the storeServletRequestResponse() method before you use the  
ApplicationStateManager.

You can do that using CSS 3 and the nth-of-type() pseudoselector

I've always used another page for that purpose but that seems a nice

Exception accessing T5 Registry from other servlet

2009-12-07T10:31:44Z

Hi!

I'm trying to integrate my T5 IOC Registry with the non-T5 part of our
application. But when I try to actually use services that are perthread and
depend on session data, I get the error listed below. It seems that the
request or the session hasn't been initialized properly for the request.
This is a request for a page that is in my "ignoredPaths" list, so it is
ignored by tapestry. Is that the reason why I get this error? Or is it
perhaps affected by the order of my servlet filters?


Caused by: java.lang.NullPointerException
	at $Request_12568a717d3.getSession($Request_12568a717d3.java)
	at $Request_12568a717a6.getSession($Request_12568a717a6.java)

Here's the service implementation with the error:

public class UserWrapperImpl implements UserWrapper {

private final ApplicationStateManager asm;

  public UserWrapperImpl(ApplicationStateManager asm) {
    this.asm = asm;
  }

  public User getUser() {
    return asm.get(User.class);
  }

}

BeanEditForm - multi col?

2009-12-07T10:01:26Z

Hi,

I'm trying to maximise screen real estate in some pages and was wondering if
there is an easy way to make the BEF multi-col - even two col would do the
trick - any getter annotations etc. to get it to close one div and start
another - thanks.

Jim.

Invoking javascript when a zone is updated

2009-12-07T07:14:42Z

Hi!

I have a "AddThis" section within a zone that I am updating.

A zone update does not execute the javascript section and my question
is if anyone has a workaround for this?

One could argue to move the section out of the zone but as the design is
made
that is not so easy.

Is there a way to solve this in a zone?

Thanks in advance!

Access the Tapestry IoC from another servlet

2009-12-07T06:08:07Z

Hello!

I'm writing an application that has both a T5 web app and also a Restlet servlet in the same
project. So T5 is the servlet-filter and the Restlet is an actual servlet. To allow both to
co-exist I've configured the T5 AppModule to ignore anything with /rest/ at the beginning
of the request - and that all works fine.

The issue is that I would really like to use the Tapestry IoC from the web app in my Restlet
servlets. Is there anyway to do this? I tried following the instructions for non-web registry
creation (added the code to the restlet initialization) and got the message:

"[ERROR] internal.SerializationSupport Setting a new service proxy provider when there's already
an existing provider.  may indicate that you have multiple IoC Registries."

So I think the Restlet actually sees the registry from the web app running. Is that true -
and if so can I get access to it?

Sorry, I'm a bit new to all this configuration.
Thanks for any help!

You're right, my bad. I was looking at the form injector when I
replied. It doesn't raise an event and so I used the show hack. I'm
using ZONE_UPDATED_EVENT for my zones...

You would need to implement your own ValidationDecorator. I just thought  
of it yet. It would be a better solution to your specific problem. There  
were some messages in this mailing list about it. The Tapestry sources are  
other nice places to see some examples about it.

It would be easier in the fields.

I don't know, but maybe you can use CSS for that.

I don't know.

Thanks for the hint. I've thought in this direction as well but was not sure 
if it would be possible at all. I like the mixin strategy because writing my 
own components seems to duplicate lots of the tapestry-components.. or do I 
miss s.th.?

About the mixin I have some questions:
 * where would you add it? On the fields or on the form? 
 * How do I remove / replace the tapestry-generated error popups with the in-
place error message?
 * Do I need to re-invent the client-side stuff?

Lots of questions, sorry...

I can think of two ways: using your own component to get the validation

Customize markup of client side validation

2009-12-06T20:10:24Z

Hello,

I want to overwrite the markup that is generated from tapestry for client side 
validation. To be more detailed, I need to integrate the forms.css of the YAML 
css framework:
http://www.yaml.de/en/dokumentation/css-bausteine/formularbaukasten.html

To use it the right way, it is not enough for me to overwrite the .t-error and 
.t-error-icon styles, but I need to change what markup is generated if there 
is an error.

Also I want to get rid of the popup boxes. The final markup should look like 
this:

                My error message! 
                FieldText

What would you suggest how to accomplish this?

Thanks in advance,

Re: Tapestry - hibernate problem

2009-12-06T17:37:04Z


My mapping are ok, because yesterday I used eager fetching on all collections
and it worked, I just removed every eager mappings and create criteria for
all one level criteria, problem is when I try to go deeper...

It seams that problem is that session is closed when I try to fetch data...
It seeams that tapestry is closing hibernate sessions automatically. 

Someone told me to implement open session in view... Any suggestion about
that matter? 

Tnx for your fast answers :)

Re: How to insert in a Grid

2009-12-06T16:51:30Z

Thanks for the example, Thiago.

I modified your code it to make it work with my example.
Now, to make my tml[1] work I edit the mixin[2] to render the foot-block 
and then move it to the right place.
I had to use two less beautifull workarounds. The first one was that 
marker tag. Although the documentation sais the "MarkupWriter is more 
like a cursor into the DOM tree" I didn't find out how to get the 
cursor's position. So that's why there is a marker tag. Now I can find 
the previously rendered tfoot-block and grid-table, which are relative 
positioned to the marker.

Then comes my second workaround. Initially I wanted to call 
tfoot.moveToBottom(gridTable); but that causes a stack overflow because 
this move-method does not delete Node#nextSibling, only the previous 
lastChild's nextSibling - which was null. The nextSibling of the Element 
"tfoot" in my code points to the grid-div! So this causes some 
endless-loop. Is this worth a Jira?

Anyway, as my code is not perfect, yet, I'd appreciate any suggestions 
for improvement :)

I know, but there is so much nice functionality in the Grid that I don't 
want have copy-pasted into some custom component. I rather write some 
Frankenstein-Mixin than copy-paste your work ;)
An AbstractGrid would be nice!

Re: Tapestry - hibernate problem

2009-12-06T14:47:19Z

Hi,

You should check your mapping to be sure the many-to-one relationship 
between "comment" and "user" is correct, and verify your database table 
"comment" contains an existing foreign key to the user table.

Best thing to do is to run your Criteria in a JUnit test.

Nicolas.

Hi,
Looks more like an issue with your criteria. Have you tried to use 
FetchMode.EAGER instead?

Tapestry - hibernate problem

2009-12-06T12:19:02Z

Hi all,

I have a little problem.

I'm using hibernate criteria to fetch list of objects that I want to display
in loop component. (enclosed in my commentModule component)

Criteria criteria = getManager().createCriteria(CommentBean.class);
criteria.setFetchMode("user",FetchMode.JOIN);

this criteria should return list of commentBean objects and associated user
object (as said in hibernate documentation),

BUT

when i call in loop element comment.user.username to optain username of user
that posted comment I get this error:

Render queue error in Expansion[PropBinding[expansion
collaborators/Details:commentsmodule(comment.user.username)]]: Property
'user' (within property expression 'comment.user.username', of
me.xxx.xxx.components.CommentsModule@eaabad) is null.

I tried all sorts of thing but I'm not sure what to do next... Is this
problem with tapestry and is there some sort of work around?

Context missing in onUploadException

2009-12-06T09:31:32Z

If a file upload triggers UploadException (eg. because file exceeds max size) then onUploadException(..)
is called without calling onActivate(..) first, so when we're in onUploadException(..) we
don't know the page context. 

 I want to redisplay the page, with exception message, but how can I redisplay if I don't
know the context?!?!  Any suggestions?

Incidentally, the doco warns about this ( http://tapestry.apache.org/tapestry5/tapestry-upload/
) but doesn't give a solution.

Cheers,

Geoff

And what will happen if the user has disabled JavaScript?

 -> Nothing

That is doubtless not the thing which the page author wants to happen.

I wouldn't say it's lame, it's just the way it is. No other event
system I know of would ever allow ordering event handlers. In fact,
treating all handlers equally allows an option for executing them in
parallel (even if current Javascript engines don't do that).

First of all, thanks for the well-written wiki page Chris, it's very
informative. I'd think the right way to solve the problem is to use
event propagation as intended. That is, in the case of confirm(), you
should target the element inside of your actionlink - for example:

delete

Then add a handler for the nested element:
Event.observe($('confirmDelete'), 'click', function(event) {if
(!confirm('are you sure to delete this record ?')) event.stop();});
to stop the event from being propagated to the actionlink handler.

You could probably attach the confirm mixin to an Any component
outputting a span. If you put a button inside, it'd be even easier
since you could just do onclick="return confirm(...);". Unfortunately
it's not possible, or at least not trivial, to create a mixin that you
could attach to the parent element but make it listen to a "click"
event of a nested element - and I don't think it would be cool if the
mixing would programmatically modify the parent element (since that's
how I see you could get it done if you really wanted to).

You can decorate and advise the MarkupWriterFactory service to do that.  
Anyway, I don't know if there's a JIRA for that alrady. If not, please

I think the best way simpler way is to have a javascript that opens
page B after X seconds.

forward to page after delay

2009-12-05T13:54:16Z


Hi,
I m new in tapestry and try to create confirmation page A which redirects to
page B after 5 seconds. Something like: "Your login was successful. Now You
will be redirected to the indexpage."

I tried to realize this in the onActivate() method with Thread.sleep or
(java.util.Timer) but it doesn't woks. I takes 5 seconds to load the
(index)page but in this time I don't see the confirmation page :(

Thanks for help and sorry for my bad english.

2009-12-05T12:55:57Z


Thanks for your reply Thiago.

The mixin method would work I guess but what I'm trying to do is remove the
'name' attribute generated by the Form component (because it is not valid in
the Strict Doctype).  I don't want to add a mixin to every form in my
application.  Is there any way that I can register this with the framework
when the application starts?  I.e. get hold of the MarkupWriter so that I
can call its setListener method?

Re: ZoneUpdater -> null strings ...

2009-12-05T10:24:35Z

Hi!

I just copied the JumpStart example ... i.e. copied ZoneUpdater.java +
ZoneUpdater.js.

My html is also using jquery in noConflict() mode.

My tml looks like ...

.tml
====



Currently I have added a "dummy" in my action methods which works.

But it would be nice to sort it out.
