RF-7542 is a duplicate of RF-7583, please reopen RF-7583 and add affected version.
If this issue really exists in 3.3.3.Final then you are in problem, cause there are no plans to release next RF 3.X. Even if anybody would fix it you would have to work with 3.3.4-SNAPSHOT, so would need to compile it on your own.
Please double check if you're attaching the menu right. Please share your facelet.
Thanks. It appears that this is a bug in myfaces 2.0.6. It adds a column index to the id of everything in the column. So when RF goes to look for the context menu it uses the menu's parent to construct the expected id of the context menu and therefor does not match. Tried with the Mojarro reference JSF 2 implementation and it works correctly. I will try a more recent build of myfaces 2 to see if that addresses the problem.
