Hi All, I'm currently developing an application-like project using Seam 1.1 beta 1 (CVS ver. 30/10), JBoss 4.0.5, Myfaces and Facelets (I removed everything about Tomahawk because of too many headaches).
This project provides its services with a tabbed layout (I made a first tryout using Tomahawk tabbed pane component... But too many strange behaviours, waste of time and headaches) allowing the user to open a tab (or give the caption to an already opened) from a menu or from another tab keeping the current state (for example the results of a search) of each of them (it is not reasonable that a search page does not keep track of the last search request if I move on a detail page for a result item and then I move back to the search page). To achieve this goal using Seam I want to create a conversation for each tab currently opened. In order to resume the current state (what the user did on it) of the selected tab I tried to create conversations with an explicit ID (Seam should detect that there is a conversation with the same identifier, resume that one and not call again the begin method). To check the capability I created a simple project which merely creates a list of links which call the same action (the @Begin method of my conversation with a static id... in this example). I was expecting that the first time Seam creates the conversation and the others refers to it, but this is the result of my tryouts: 1 - The first, the best possible for my needs and probably what-I-cannot-do tryout: The h:commandLink action was a method of a session scoped stateful bean (something like a session handler) with the logics to retrieve the outcome related to the tab-action and, using the page-action model (faces-config.xml + pages.xml), call the begin method of the correct conversation. Unfortunately this approach fails because when the Manager tries to set the id of the current conversation, the conversation list is unmodifiable and I get an UnsupportedOperationException; but this is reasonable because Gavin told in more than a post that the conversation is strictly related to the request boundaries and then probably when Seam tries to set the conversation id the request handling is in a state that makes this operation unsafe (even if there is a redirection to a different action handler, and should seem a different request I think that the http request is only one and the redirection is an internal handling of Seam). 2 ? Not the best? but a good one: The h:commandLink action is the begin method of the conversation which handles the tab behaviour, the first time the action is called Seam reads the id, does not find it in the conversations list and creates the conversation with the given identifier (and calls the begin method). If the user clicks the link another time Seam finds the conversation and switches to that one without invoking the begin method. Unfortunately also this approach fails, indeed, Seam throws an exception when I click the link the second time saying to me that is unable to render a view for a null viewId (I like the Seam logics of not to call again the begin method but I hoped that the outcome was stored and passed to the Seam rendering handler to render the same view). Probably I left something and I hope that someone can help me to understand where my logics is wrong and how can I solve this problem, but now? a little bit of code to have a wider vision of the problem: Layout.xhtml (the page with the list of links) | <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> | <html

Jamiroquai * (-1) = moving without travelling AKA little workaround but same results: This solution is exactly the same as the previous one except for the action management. Idea: ok, when the conversation is resumed the begin method is not called anymore and the outcome is not set, well, but if the begin method is an actionListener and the action of the commandLink is a static outcome? Fails in the same way? Any help is really appreciated!
