• Type: Bug
• Status: Continued

• Component/s: - Flowscript
• Environment: Operating System: Linux; Platform: PC
• Bugzilla Id: 36322
• Assignee: Unassigned

Description

I use Rhino 1.6r1 (from trunk svn) in my cocoon. I get a NullPointerException in
that case :
I first call a flow function to display a jx template using a continuation.
Then I post the form (and the continuation) to a pipeline calling a flow
function that does a cocoon.sendPage to a pipeline calling the continuation.
Then, I does some things in the flow and I display the jx template again.

The first time I post the form : OK it's working.
The second time I post the form : A NullPointerException is thrown !

Here is the full java stacktrace :
