I was thinking perhaps I could leverage the Seam Remoting capabilities. Once I selected the items I need, I press a command button <s:commandButton action="#{mybackingbean.process}" onclick="setSelection()" /> I implement a setSelection() javascript function that retrieves the selection from the trinidad component and submits it through seam remoting capabilities. The only bummer with this is I need the AJAX call to be synchronous (SJAX) to make sure that when the action on the command button is processed I already have updated the server state with the selected items. Is it possible to use Seam remoting synchronously ? I know this is generally a bad thing to do but in my case it would help me solve my problem.
