> Null locator in EffectPipe triggers NPE
> ---------------------------------------
>
> Key: COCOON-1651
> URL: http://issues.apache.org/jira/browse/COCOON-1651
> Project: Cocoon
> Type: Bug
> Components: Blocks: Forms
> Versions: 2.1.8
> Environment: Operating System: Linux
> Platform: PC
> Reporter: Tom Green
> Assignee: Cocoon Developers Team
> Fix For: 2.2-dev (Current SVN), 2.1.9-dev (current SVN)
> Attachments: EffectPipe.java.diff, cforms-npe-bug.tgz
>
> I am getting an NPE at line 488 in EffectPipe.java which is reliably triggered
> by simply putting an XSLT transform in the template pipeline at any point
> BEFORE
> the forms template transformer. It didn't show up in the stack trace, but I
> traced it to the call to EffectPipe.beginBuffer() in cases where locator is
> null. For some reason, locator is null in case there is an xsl transform in
> the
> pipeline right before the forms transformer. I'm including a zip of the
> relevant files to recreate the problem using the stock "registration" sample
> form, as well as a simple patch that works around the NPE. I'm not sure if
> this
> is the *correct* way to fix this bug, since I don't really understand what it
> means for the locator to be null in this context, but it appears to work fine
> for me. Note that in the included sitemap you just need to comment out the
> <transform src="xsl/identity.xsl"/> and the bug goes away.
