Sorry, my english is not very good.
When I hide the panel, I generate an ajax event.
In the ajax event, I execute a query, but the screenmask is not shown.
I have 2 options:
- do it in the way you told me in the prior post
- set the screenmask.enabled of the panel to true
tested the second way, it works, but I don't know if its is the best way.
But now, works, thanks.
