Subject [jira] Created: (TOMAHAWK-1257) Tomahawk datatable not refreshing after error
Date Tue, 20 May 2008 13:26:57 GMT
Tomahawk datatable not refreshing after error     

                 Key: TOMAHAWK-1257
             Project: MyFaces Tomahawk
          Issue Type: Bug
          Components: Extended Datatable
    Affects Versions: 1.1.6
         Environment: Windows XP, IBM Rational Developer 6.01.
            Reporter: David Moberg

I have a JSF application that is using a Tomahawk datatable. Everything works perfectly except
for after an error has occurred. The error can be conversion or validation error or something
else, it does not matter. Once one of these errors occur and the page reloads with the error
message it is no longer possible to update the datatable.

When I submit the page with new filtering options (and of course removing what caused the
error) the page just reloads but nothing changes. The error message no longer displays.

Here is the datatable:

<t:dataTable var="request" styleClass="datatable fullwidth"
rowClasses="list-row-even, list-row-odd"
columnClasses="column-1, column-2, column-3, column-4, column-5, column-6, column-7, column-8,
column-9, column-10, column-11, column-12, column-13, column-14, column-15, column-16, column-17,
rows="#{BuViewBean.numOfRows2}" value="#{BuViewBean.list}"
id="dataTable" preserveDataModel="false" preserveSort="true"

The main problem is that once I have had an error on the page, the BuViewBean.list method
is never called. I have verified this with debugger.

What is weird is that BuViewBean.numOfRows2 is called and all other beans on the page are
called. Basically all getters and setters are executed except for BuViewBean.list.

And as I mentioned above, everything works perfectly until an error is encountered.

I can also add that I added a Phase Listener and was able to determine that a successful reload
of the datatable (pre error) contains the exact same phases as the unsuccessful reload after
the error has been generated.

This sounds like a bug in Tomahawk datatable to me.

I am using Tomahawk-1.1.6.jar.

Ok, I tried to do some debugging but with no success. I am not sure what is going on.

I was able to determine that the createDataModel() method in HtmlDatatableHack.class does
not get executed after an error has occured. I was not able to tell from where/how the createDataModel()
method is called. Some code is preventing the datatable from being refreshed.

I can also add that I tried to switch to the standard datatable (h:) and that works as it
should but does not have any of the fancy features that Tomahawk datatable has.

Am I really the first person encountering the problem?
