Indeed, I'm in the same boat. Hopefully we'll get an explanation here. In the orignial posting, I saw in supplier.xhtml | <h:commandButton action="#{supplierMaintenance.save}" value="Save"> | <s:conversationPropagation type="join" /> | </h:commandButton> Looks like desperation, I don't think you should have to do the "join" there. You might have to put the conversation id there? But, I think that's only for links. In any case, sorry, I don't have an answer for you. I'm in the same situation. I'm finding it quite frustrating that I have to waste time figuring out how to submit data in Seam/JSF....
