[jboss-user] [JBoss Seam] - About pageflow
Hello,
I ran into some trouble trying to start properly a pageflow.
First of all, let me explain the situation. I'm using JBoss 4.0.4GA with Seam 1.1.0GA
I have a SFSB that is responsible for choosing a flow and start it.
| @Begin
| public void init() {
| ...
| Pageflow.instance().begin(this.getPageflow());
| }
|
The pageflow is defined as followed:
| <?xml version="1.0"?>
|
| <pageflow-definition name="test">
|
| <start-page name="start">
| <transition to="isUserLoggedIn"/>
| </start-page>
|
| <decision name="isUserLoggedIn"
expression="#{loginAction.isUserLoggedIn}">
| <transition name="true" to="page1" />
| <transition name="false" to="page2" />
| </decision>
| ...
| </pageflow-definition>
|
The flow is started in the RENDER_RESPONSE phase, so I can't use <start-state>
The issue I had is that the flow didn't start properly (I was redirected to an error
page) but could not see anything wrong in the logs.
So I looked into the code, more exactly at the begin method of Pageflow.java.
| public void begin(String pageflowDefinitionName)
| {
| if ( log.isDebugEnabled() )
| {
| log.debug("beginning pageflow: " + pageflowDefinitionName);
| }
|
| processInstance = PageflowHelper.newPageflowInstance(
getPageflowProcessDefinition(pageflowDefinitionName) );
|
| //if ( Lifecycle.getPhaseId().equals(PhaseId.RENDER_RESPONSE) )
| //{
| //if a pageflow starts during the render response phase
| //(as a result of a @Create method), we know the navigation
| //handler will not get called, so we should force the
| //pageflow out of the start state immediately
| //TODO: this is not actually completely true, what about
<s:actionLink/>
| //pi.signal();
| //}
|
| setDirty();
|
| Events.instance().raiseEvent("org.jboss.seam.beginPageflow." +
pageflowDefinitionName);
|
| storePageflowToViewRootIfNecessary();
|
| }
|
There is a comment about what I believe is my case. I then solved the problem by adding
the following line at the end of the SFSB init method:
| Pageflow.instance().navigate(facesContext, null);
|
Now everything is fine but I believe this should be fixed in Seam. It seems to me that you
guys know about it already, so any plan yet?
Regards,
Richard
