[jira] [Created] (TRINIDAD-2232)
ComponentContextManagerImpl.resume() fails on null _stack member variable
ComponentContextManagerImpl.resume() fails on null _stack member variable
-------------------------------------------------------------------------
Key: TRINIDAD-2232
URL: https://issues.apache.org/jira/browse/TRINIDAD-2232
Project: MyFaces Trinidad
Issue Type: Bug
Affects Versions: 2.0.2-core
Environment: tomcat 6.0.20, myfaces 2.0.11, java 1.6.0_22, trinidad svn r1294382 (2.0.2-snapshot)
Reporter: Caius Gran
I couldn't figure out a simple case for reproducing this, but judging by the debugging I did,
the reason seems to be a pushChange()/popChange() -cycle of some children (or grand-children or etc)
components as a side effect leaving the "_stack" member variable null.
An example resulting stack trace:
java.lang.NullPointerException
