APEX

Hi,

I am using this inside a function that returns a boolean:

apex_application.g_print_success_message :=
'Error message';

However, the message is not shown on the screen.
Is this another "undocumented feature" ?
The functions cancels the transaction, which is good, but the users don't get a message,
so you can imagine, this is rather frustrating.

It even doesn't work when I call the message from with a normal procedure.

Can it have something to do with the APEX_UTIL.CLEAR_PAGE_CACHE I use?
