Provide a way to nest pageflows
-------------------------------
Key: JBSEAM-2854
URL: http://jira.jboss.com/jira/browse/JBSEAM-2854
Project: JBoss Seam
Issue Type: Feature Request
Components: BPM, Core, JSF Controls
Affects Versions: 2.0.1.GA
Environment: All
Reporter: Marcell Barbacena
The current behaviour of pageflow subprocess tag is to include the pageflow definition in the the current flow, meaning that the parent pageflow is paused until the included pageflow ends.
However, sometimes it is desired that the parent pageflow do not "pause" and that the included gain its own flow.
The semantics of this nested pageflow is:
- when starts: provided a nested conversation from the parent pageflow.
- when ends: go back do the state before the nesting. If the parent pageflow is not associated in any way to the nested, its flow goes without interfering with the nested.
E.g.:
Parent directed graph: startpage1->page1; page1->page2; page1->nested; nested->page2; page2->page3; page3->endpage1;
Nested graph: startpage2->page5; page5->page6; page6->endpage2
Then we can have:
parent: startpage1->page1;
parent: page1->nested;
nested: startpage2->page5;
nested: page5->page6;
parent: page1->page2;
parent: page2>page3;
nested: page6->endpage2
nested:endpage2->page2;
parent: page3->endpage1;
nested: page2>page3;
nested: page3->endpage1;
See that the nested pageflow gains his own flow, i.e. independent of the parent.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3056) JPDL navigation and seam

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.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2232) Reduce debug log level for events
by Christian Bauer (JIRA)
Reduce debug log level for events
---------------------------------
Key: JBSEAM-2232
URL: http://jira.jboss.com/jira/browse/JBSEAM-2232
Project: JBoss Seam
Issue Type: Task
Components: Core
Reporter: Christian Bauer
Priority: Critical
Debug logging with Seam 2.x is completely useless. The most critical information in the debug log is the instantiation and lookup of components, however, if you enable DEBUG for
org.jboss.seam.Component, you get thousands of these:
12:26:06,282 DEBUG [Component] instantiating Seam component: org.jboss.seam.core.events
12:26:06,282 DEBUG [Component] initializing new instance of: org.jboss.seam.core.events
12:26:06,282 DEBUG [Component] done initializing: org.jboss.seam.core.events
We need to exclude the event firing from debug logging, even if we hardcode it. And, are these events really useful? I have no idea why and when I'd want to listen to "context variable initialized" events.
