Hi,
we have a problem that used to be addressed by @Conversational. However with Seam 2 I am not sure how to address it. The scenario:
I have a current long running conversation. During this conversation a page (view.xhtml) is displayed. view.xhtml contains an s:link with an action in a stateful bean:
<s:link action="#{contentManagementBean.editContent}"
| id="editContents"/>
Based on the outcome of editContent the pages.xml displays the appropriate edit page.
The stateful bean has an @In(required=true)
| @In(required = true,value="selectedGroupingForView")
| @Out(required=true)
| private Grouping selectedGroupingForView;
However, a problem occurs when the long running conversation expires, the various elements in the conversation context are removed, and when the uses then selects the s:link. Obviously the stateful bean cant inject the "required" values, which results an exception.
Is there anyway to protect/prevent this type of problem ?
Thanks
Louis
