[cforms] NPE within Forms sample block when debugging enabled (Cocoon 2.1.5-dev)

[Olivier Lange <ol...@petit-atelier.ch>]

Hello all

I am a CForm newbie. I ran accross a NPE while trying to
run the CForm 'Various (Flowscript)' sample with Flowscript
debugging enabled.

Is something broken with these sample or did I overlook
some setting?

All the sample work fine when debugging is disabled.

The 'Various (Action)' sample has a similar problem:
http://localhost:8888/samples/blocks/forms/form1
It throws a NPE when debugging is enabled.

* Details

I built Cocoon 2.1.5-dev from CVS HEAD today, enabled
FlowScript Debugging as suggested hereafter and started Cocoon:
http://wiki.cocoondev.org/Wiki.jsp?page=DebugFlowScripts

Cocoon throws a NPE when I request the following page:
http://localhost:8888/samples/blocks/forms/form1.flow

The debuggers starts, but when I resume debugging (Go),
Cocoon throws the following error:

Error displayed:

"resource://org/apache/cocoon/forms/flow/javascript/Form.js", line 47:
uncaught JavaScript exception: at handleForm
(resource://org/apache/cocoon/forms/flow/javascript/Form.js, Line 186) at
Form (resource://org/apache/cocoon/forms/flow/javascript/Form.js, Line 47):
java.lang.NullPointerException

The other samples work fine (the Locale samples put aside,
and only if they are run before the error is thrown).
