I get my new tab; unfortunately this is accompanied (in the log) with an assortemnt of seam conversation errors, which indicate that the new tab is trying to render the original page "page1.xhtml", not the outcome of the action "page2.xhtml". These errors make sense: since I did not propagate the conversation, the seam components used to render the original page are not available in the new conversation.
The action always returns "page2.xhtml" (it is hard coded) so it appears as if the target _blank and switchmode server confuse the navigation...? It seems like a navigation error to me;
Any ideas? I have spent way too much time on this already :(.
