Beth,

Can you (or some committer) please apply the patch to both CDT branches (4.0 and HEAD), if the patch is ok.

Regards,

Re: [cdt-dev] Template engine can't see my        pagesAfterTemplateSelectionProvide class





Great! That works; my class is now getting called.  will have to actually
put in a page there now. :)
I do notice that  getCreatedPages is called, but not createAdditionalPages
which the comments imply would get called first to construct them.
I can handle it either way.
Is that right?

Hi Beth,

I have attached a fix for this problem, not using the reflection API
directly. Originally it was implemented in the "Eclipse way" to create the
executable class using ExtensionRegistry, when I implemented it as a
standalone plugin. But during the integration of TE into new project model,
and the seperation of core and ui parts of the TE resulted in calling the
Reflection API directly. I fixed this problem now with the following patch.
Did you open a defect for this issue? If not, please ask a committer to
apply this patch, if you found it's ok.



Regards,
-Bala

I'm getting a ClassNotFoundException when the template engine tries to load
my  pagesAfterTemplateSelectionProvider class.
The class is indeed there.

java.lang.ClassNotFoundException:
org.eclipse.ptp.pldt.wizards.wizardPages.MPIPageProvider
    ....
    at org.eclipse.cdt.ui.templateengine.Template.getExtraCreatedPages(
Template.java:147)

<template
          filterPattern=" "
          id="org.eclipse.ptp.pldt.projects.MPIhelloWorldCProject"
          location="templates/MPIhelloWorldCproject/template.xml"
          pagesAfterTemplateSelectionProvider=
"org.eclipse.ptp.pldt.wizards.wizardPages.MPIPageProvider"
          projectType=."org.eclipse.cdt.build.core.buildArtefactType.exe"
>
    </template>

in Template.java it's using Class.forName instead of the eclipse class
loader

//e.g.
pagesProvider="org.eclipse.ptp.pldt.wizards.wizardPages.MPIPageProvider";
Class clazz = Class.forName(pagesProvider);
instead of something like.

ExtensionRegistry.createExecutableExtension()




Have you been able to get this to work using a class in another project
from template engine, as the pagesAfterTemplateSelectionProvider class?

Are these changes what you were talking about that will be coming in 4.0.2?
