JPDL navigation and seam
------------------------
Key: JBSEAM-3056
URL:
http://jira.jboss.com/jira/browse/JBSEAM-3056
Project: Seam
Issue Type: Task
Components: BPM
Reporter: Florian Keusch
hi
In our applications we have a navigation menu. When we use seam and some jpdl pageflows we
have the following problem:
if we leave the pageflow with a <s:link propagation="end"> (e.g. clicking
on the menu), then the pageflow conversation is ended but also an illegal navigation
exception is thrown.
This issue was described on the seam framework:
http://www.seamframework.org/Community/ProblemWithJPDLIllegalNavigation but I could not
find it in this Jira.
It's not solved. In the code (PageFlow.java) there's a TODO where the illegal
navigation ecxeption is thrown:
//now check that the restored view id matches what we expect
//from the pageflow node
//TODO: we need some way to disable this check, since users
// might want some adhoc nav in and out of a pageflow?
String viewId = Pages.getViewId(facesContext);
if ( !viewId.equals( getPage().getViewId() ) )
{
illegalNavigationError();
}
If we use <s:link propagation="none"> in our menu navigation then this
will not cause a illegal navigation exception, but in the background the conversations are
still there not ended.
