Problem with pageflow

[jdestef]

Hi,

I'm having a problem with my pageflow. When I invoke to annotated begin method the pageflow does not happen. The same page I was just view is redisplayed.

My page flow file looks like this:

<pageflow-definition name="encounterfind">

 <start-state name="start">
 <transition to="encounterlist"/>
 </start-state>

 <page name="encounterlist" view-id="/view/encounterlist.xhtml" redirect="true">
 <transition name="encounterlist" to="encounterlist"/>
 <transition name="encounterdetail" to="encounterdetail"/>
 <transition name="bookinglist" to="bookinglist"/>
 </page>

 <page name="encounterdetail" view-id="/view/encounterdetail.xhtml">
 <end-conversation />
 </page>

 <page name="bookinglist" view-id="/view/bookinglist.xhtml">
 <end-conversation/>
 </page>

</pageflow-definition>

My bean class looks like this:

@Stateful
@Name("addfindencounter")
@Conversational(ifNotBegunOutcome = "logout")
@LoggedIn
@Interceptors(SeamInterceptor.class)
public class AddFindEncounterAction implements AddFindEncounter, Serializable {
.
.
.

@Begin(join=true, pageflow="encounterfind")
 public String start() {
 System.out.println("In findencounter.startAdd");
 userSessionStuff.setFindMode(false);
 System.out.println("In findencounter.startAdd before return");
 return "encounterlist";
 }

I know the method executes as I see the output in the log.

I have added the following to my web.xml and included the jbpmXX.jar file in my ejb jar file.

<listener>
 <listener-class>
 org.jboss.seam.servlet.SeamListener
 </listener-class>
 </listener>

 <!-- 120 second conversation timeout -->
 <context-param>
 <param-name>org.jboss.seam.core.conversation.timeout</param-name>
 <param-value>120000</param-value>
 </context-param>

 <!-- Global JNDI name pattern for JBoss EJB3 (change for other servers) -->
 <context-param>
 <param-name>org.jboss.seam.core.init.jndiPattern</param-name>
 <param-value>patc/#{ejbName}/local</param-value>
 </context-param>

 <context-param>
 <param-name>org.jboss.seam.core.init.componentClasses</param-name>
 <param-value>org.jboss.seam.core.Jbpm</param-value>
 </context-param>

 <context-param>
 <param-name>org.jboss.seam.core.jbpm.pageflowDefinitions</param-name>
 <param-value>addfindencounter.jpdl.xml</param-value>
 </context-param>

The are no error in the log file. I do see a message that jbpm is starting:

[JbpmConfiguration] using default jbpm configuration with minimal services enabled. to enable persistence services, provide a jbpm.cfg.xml on the root of the classpath. see userguide, chapter 'Configuration'
23:26:12,339 INFO [Initialization] done initializing Seam

Any thoughts would be appreciated.

This won't help you, but you are not alone

What happens when you have @Begin(join=false, ....)

I bet you already have a conversation in progress.

[ido_tamir]

In my case:
when @Create is present on the @Begin(join=false) then I immediately get an exception.
when @Create is not present on the @Begin(join=false) method on the second click I get an exception.

when @Begin(join=true) I can click as much as I want (with and without @Create).

But I do not get a redirect. My best bet its a configuration issue,
but I also know that once I get into a pageflow it works as expected and redirects happen.

Hi Gavin,

Yes, that was it, I already had a conversation going.

Tx for the help.

[gavin.king]

np, should probably add a FAQ on this.

You know how to force a new conversation to be started, right?

The pageflow only takes effect when a new conversation starts. The problem is that a conversation is already in progress.

[ido_tamir]

Maybe I missunderstood something completely.

When I add a navigation-rule in faces-config.xml that makes the first transition from the pageflow start-state to the first pageflow wait-state, then it works.
Is that how it should work? Because I had the impression that
the pageflow itself should take care of the first transition irrespective from which page it got started.

I am pretty confident that in the case when there is no @Create on the @Begin(join=false, pageflow="flow") start-method I have no conversation already started when I activate the method (no exception). I do get an exception when I call the method a second time, indicating that the first activation created a long running conversation, but no redirect.

>You know how to force a new conversation to be started, right?

<h:commandLink action="#{pf.begin}" value="start">
 <f:param name="conversationId" value="new"/>
</h:commandLink>

I just tried it but it does not help.
Sorry for being a bit slow and stubborn.

Thank you for your answers.

Yes, your understanding is correct. I will take a look at your JIRA issue when I get a chance.

[gavin.king]

Yes, it was a bug, now fixed in CVS.
