Pageflow Configuration?

connerjohn Aug 2, 2006 4:30 PM

I'm trying to follow the Number Guess example but can't seem to make pageflows work in an example applications. I took a shell from an application that I created earlier that works and added the pageflow configuration items. Any thoughts on what I'm missing.

components.xml

 <component class="org.jboss.seam.core.Jbpm">
 <property name="pageflowDefinitions">pageflow.jpdl.xml</property>
 </component>

facelets

pageflow

<pageflow-definition name="testflow">

 <start-page name="displayPageOne" view-id="/page1.xhtml">
 <redirect/>
 <transition name="test2" to="selectedAddr">
 <action expression="#{processFlowNameAction.selectAddr}" />
 </transition>
 <transition name="test3" to="newAddr">
 <action expression="#{processFlowNameAction.newAddr}" />
 </transition>
 </start-page>

 <page name="selectedAddr" view-id="/page2.xhtml">
 <transition name="done1" to="doneP">
 <action expression="#{processFlowNameAction.page2Action}" />
 </transition>
 </page>

 <page name="newAddr" view-id="/page3.xhtml">
 <transition name="done2" to="doneP">
 <action expression="#{processFlowNameAction.page3Action}" />
 </transition>
 </page>

 <page name="doneP" view-id="/page4.xhtml">
 <redirect/>
 <end-conversation />
 </page>

</pageflow-definition>

When I navigate to http://localhost:9090/example-app/page1.seam the page1.xhtml is displayed; but I'm not in a page flow and the buttons will not work.

Here is what is in the log

Any suggestions on what I'm missing.

I turns out I was not packaging the app corectly and the Cart.java was not being included in the *.jar. Which leads to a question:

What does seam do if it is looking for a MB and doesn't find one? Going over the log file I would have exepcted to see Seam looking for the MB "processFlowNameAction" but didn't.

what is "MB"?

Managed Bean?

If a context variable is null, JSF usually ignores it.

yes - sorry for the shorthand.
