generated MyFaces id's produce duplicates which throw exceptions in container,
rendering existing apps unusable
---------------------------------------------------------------------------------------------------------------
Key: MYFACES-1550
URL: https://issues.apache.org/jira/browse/MYFACES-1550
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 1.1.5
Environment: MyFaces 1.1.5, WindowsXP, Tomcat5.5.20
Reporter: Lisa Sanchez
Priority: Blocker
Fix For: 1.1.5
Pages that once worked (1.1.5) stopped working for some reason (within the past
week). The issue seems to be with generated id's on components.
You will see this where you load a page and then reload the same page through a
hyperlink or rendering for the second time.
There seems to be some correlation with the <f:facet tag. I have a page with a
<t:dataTable and several columns that use the <f:facet> tag to provide the
column header. The page loads just fine initially but if I reload, I get a
blank screen and the following message in my Tomcat log file.
If I remove the column header and the facet tag, I do not see the error. About
a week ago there were no problems with this page so it is something new that
has been introduced and should be fixed.
