Oracle Forms - Display message blocks rest of the code execution or message doesn't show

I'm trying to show a message on a form without success. What I'm doing is: When a new line is clicked, I use the WHEN-NEW-RECORD-INSTANCE to do some verifications and some enabling/disabling on the form and showing up the message. The problem is sometimes it does the enabling/disabling but not the message, then I click another line and it shows the previous message but doesn't do the enabling/disabling...

I've already tried some stuff like: message('message'); n := Show_alert('message');

with and without SYNCHRONIZE;

I don't think it's the code itself blocking the messages... or I'm missing something...

Doe开发者_StackOverflow社区s anyone ever had this problem? Can someone tell me the various options to display messages and their differences?

Thanks.

I managed to fix this using the WHEN-MOUSE-CLICK trigger instead. I didn't want to use this at first because when I clicked the already selected line it would show the message again but I made some code verification and fixed it. Someone can close this. thanks.
