I have a versioned object for which I'd like an error message to show up when 
an OptimisticLockException occurs. Adding an entry to exceptions.xml doesn't do 
anything because, though the OLE is thrown as seen in the log, it's 
subsequently caught by something.

I'm not merging the object in an action method, however. The update to the 
object simply occurs as the result submitting a form with an inputText that is 
bound to a property on the versioned object.

When I submit the form bound with an out-of-date object, the exception is 
thrown but there's no output on the page to indicate so because the OLE doesn't 
reach out of the Seam layer to exceptions.xml.

How can I solve this? I'd think it'd be common enough that the JBoss forums 
would have some insight, but nothing is there on this issue!

I think I could have an action method and catch the exception there, but then 
I'd need the additional method, which would just do a merge(). And then I'm not 
taking advantage of the SMPC with its mergeless updates! (But this probably 
applies to EXTENDED PCs too...)
