I'm using alfresco-1.3.0-linux-community.bin, but I upgraded my JDK to 1.5.0_09 because of problems with lucene.
Something with deleting forum discussions seems to be wrong. Here are the steps to (hopefully) reproduce the issue:
1) create a workspace as admin (e.g. test)
2) on the "more actions" icon, press "start discussion"
3) return to the workspace area, verify that the discussion icon appears
4) press this discussion icon
5) select "more actions" "delete the forum"
…now the system displays:
Delete Forum ''
To remove this forum and its topics, click Yes.
Are you sure you want to delete "null" and all its topics?
…when I press yes, I get
javax.faces.FacesException: Error calling action method of component with id delete-forum-space:_id17
caused by:
javax.faces.el.EvaluationException: Exception while invoking expression #{ForumsBean.deleteForumOK}
caused by:
java.lang.NullPointerException
Hope you are able to reproduce the error.
