components raise feedback messages - which are kept at the page level
panels render messages
at the end of request the message are cleared - so if they werent shown during the same request they are gone
if you have messages that need to span requests then you need to raise them on the session object - session.error() etc. those are kept in session until they are rendered

Hello,
I put this thread back to the light because I had a similar problem :
My site has a signin panel on the left side, and another form in the
center. Each of them has a feedback panel.
In order to avoid having the same messages displayed in the 2 panels, i
followed Igor's tip, but now every feedback in one panel deletes the
other's content...
Please how can i solve this ?
