Subject [jira] [Resolved] (ROL-1930) Saving Template causes Null Pointer Exception
Date Sun, 13 Nov 2011 15:09:52 GMT

     [ https://issues.apache.org/jira/browse/ROL-1930?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

David Johnson resolved ROL-1930.
--------------------------------

    Resolution: Fixed

URL: http://svn.apache.org/viewvc?rev=1201435&view=rev
Log:
This was originally a fix for "Saving Template causes Null Pointer Exception"
https://issues.apache.org/jira/browse/ROL-1930

But once I fixed the problem I found a series of other problems and ended up making some fundamental
changes in the way that Roller's new mobile template support is implemented. I will summarize.

1) The Template Edit page now uses the YUI tab control to switch between a Page's standard
and mobile template code on the client side. Both values are saved on the client-side and
switching tabs no longer causes a page refresh.

2) Instead of determining the device-type and then injecting the right template code into
the Roller Page object, which could cause other requests to get the wrong data inside the
Page object, we now determine the device type and pass it down deep into Roller's rendering
engine. At the RollerResourceLoader level we use the deviceType to fetch the correct template
code for the deviceType.

3) Type is no now an enum called DeviceType and the variable is called deviceType instead
of "type" everywhere

>    Affects Versions: 5.1
>            Reporter: David Johnson

> Steps to reproduce:
> 1) Upgrade from Roller 5.0 to Roller 5.1 via normal upgrade process
> 2) Login and edit one of your templates
> 3) Save your template and you'll get an error, if you look in the logs you will see that
it is a Null Pointer Exception
> This is caused because the Template does not have a "Template Code" object associated
with it yet. 
> One possible way to fix this is: if a template code object is not found, then create
a new one.
