AndroMDA/JIRA Created: (JSF-35) wrong maxTableRows preferences type cause ClassCastException in jsp

wrong maxTableRows preferences type cause ClassCastException in jsp
-------------------------------------------------------------------

         Key: JSF-35
         URL: http://jira.andromda.org/browse/JSF-35
     Project: JSF cartridge
        Type: Bug

    Reporter: Luca Dall'Olio
 Assigned to: Chad Brandon


This topic is discussed in this forum thread :  http://galaxy.andromda.org/forum/viewtopic.php?p=23460

using a table to display a list of items generates the following JSF code (extract):
    <af:table allDetailsEnabled="true" var="row" bandingInterval="1"
              banding="row" value="#{fmtProfiles}"
              rows="#{preferences.maxTableRows}" width="90%">

When the page is loaded, the following exception is thrown:

Code:

10:34:16,850 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
java.lang.ClassCastException: java.lang.String
        at oracle.adf.view.faces.util.ComponentUtils.resolveInteger(ComponentUtils.java:83)

This exception is caused by the
Quote:
rows="#{preferences.maxTableRows}"
attribute in the
Quote:
<af:table ...>

The corresponding bean is by default Preferences.java, generated by the Preferences.java.vsl velocity template; the generated maxTableRows field has the wrong type, should be  int but it is String. This is the cause of the exception. By replacing the value with a static 10 everything is fine.

It looks like the jsf2 cartridge has a workaround for this, simply altering the vsl template

Pat Casey commented on JSF-35:
------------------------------

Is it possible to apply this patch to the 3.4-SNAPSHOT version?  I tried to use the snapshot last night and found this problem still is there. I know I can patch the source, but it seems like it is a simple task to include the patch in the current development version.
