1.5.2 - velocity error in PipelineSreen_<CustomPipeline>_add.vm

[Kate]

Hi Mohana,

I've just installed a new instance of 1.5.2, and I'm running into some
issues when I try to add a custom pipeline with custom add and launch
screens. Namely, when I attempt to add the pipeline to a project, I
get a number of velocity errors due to the fact that $newpipeline is
not defined in the context. e.g., " RHS of #set statement is null.
Context will not be modified. screens/
PipelineScreen_StdBuildNunda_add.vm [line 114, column 1]". Line 114
reads: #set ($schemaType = $newpipeline.getSchemaElementName()). This
same pipeline screen used to work in 1.4.

If I add a pipeline without a custom screen, however, this issue
doesn't arise. So, in PipelineScreen_add_project_pipeline.vm,
$newpipeline is defined in the context.

I see that PipelineScreen_add_project_pipeline.java defines
$newpipeline, but I guess I'm unclear as to how this screen class is
called for a custom screen, so I'm not sure where to look for
hiccups.

Any thoughts?
(Log data follows)
Thanks!

Looking at the logs, I get an error in the turbine.log when I go to
the projects display page (XDATScreen_report_xnat_projectData.vm):

And I have some other velocity errors (staring right at login,
projects display page, administer pipelines, and then, when adding the
custom pipeline):

No errors in xdat.log.

For now, I decided to customize
PipelineScreen_add_project_pipeline.vm, which works well.
