NPE calling page flow action that calls JSF code
------------------------------------------------
Key: BEEHIVE-630
URL: http://issues.apache.org/jira/browse/BEEHIVE-630
Project: Beehive
Type: Bug
Components: NetUI
Versions: V1
Reporter: John Rohrlich
An NPE is generated (see stack trace below) when executing the following
sequence of events
- Raise a page flow action directly from a JSF command
- Call JSF code from the action
- Navigate to the current page
(if you call a command handler in the page backing file and raise the page flow
action from there you do not see the NPE)
A repro (which I ran against MyFaces both 1.0.7 or 1.0.9) is attached
- Edit the build to point to your beehive/ant directory.
- import runtime
- build and deploy
- hit jsfNPECallingAction/pageFlow/Controller.jpf
- click on the search button
- then click on the link labeled "Last" (last name) in the results table to sort
- this action will generate the NPE
