Subject [jira] Closed: (COCOON-1823) extend widgets in repeater yields NPE
Date Fri, 07 Apr 2006 15:21:25 GMT
     [ http://issues.apache.org/jira/browse/COCOON-1823?page=all ]
     
Bill Bruyn closed COCOON-1823:
------------------------------

    Resolution: Cannot Reproduce

Well, when I tried to build a test case to attach to the issue, I couldn't make it fail. 
Went back and tried the initial case and that's working agin as well.  One of those things...
 :o|

Apologies for the noise.

Anyone?
