Dialog throws NullPointerException when tr:poll updates main page
-----------------------------------------------------------------
Key: TRINIDAD-1112
URL: https://issues.apache.org/jira/browse/TRINIDAD-1112
Project: MyFaces Trinidad
Issue Type: Bug
Affects Versions: 1.0.8-core, 1.0.3-core
Environment: I have demonstrated this problem in 1.0.3 and 1.0.8, I am
using the RI and JBoss 4.0.5.
Reporter: Nate Perkins
Priority: Minor
Fix For: 1.0.9-core
I'm using 1.0.3 and I have 2 pages which both use the tr:poll on a main page
and which both launch dialogs of some sort. The first page uses the 'normal'
dialog setup of using an 'dialog:*' action and using a LaunchEvent to populate
the pageflow scope with any data I need. The second page programmatically
calls launchDialog().
In the first page, if I leave the dialog open and allow the tr:poll to update
the main page and then attempt to perform an action on the dialog I get a
NullPointerException. If I take the same steps with the second page it works
with no problems. Is this a known bug or is there a recommended solution?
Would an upgrade fix this?
Here's the exception:
