Hello, I'm using the sample app generated by seam-gen (from http://www.jboss.com/index.html?module=bb&op=viewtopic&t=88326) and I'm trying to implement a second pageflow.
The easiest way to start was to copy pageflow.jpdl.xml to pageflow2.jpdl.xml, copy first-page.xhtml to ctrfirst-page.xhtml (same with second and third). The pageflow started from a different page than home.xhtml.
In the file pageflow2.jpdl.xml I renamed everything appropriate (so did I in ctr*.xhtml):
<?xml version="1.0"?>
|
| <pageflow-definition name="shellflow2">
|
| <start-page name="start2" view-id="/contractlist.xhtml">
| <redirect/>
| <transition name="first-page2" to="first-page2"/>
| </start-page>
|
| <page name="first-page2" view-id="/ctrfirst-page.xhtml">
| <redirect/>
| <transition to="first-page2"/>
| <transition name="continue-flow2" to="continue-flow-decision2"/>
| </page>
|
| <decision name="continue-flow-decision2" expression="#{flowBean2.continueFlow}">
| <transition name="true" to="second-page2"/>
| <transition name="false" to="start2"/>
| </decision>
|
| <page name="second-page2" view-id="/ctrsecond-page.xhtml">
| <redirect/>
| <transition to="second-page2"/>
| <transition name="third-page2" to="third-page2"/>
| </page>
|
| <page name="third-page2" view-id="/ctrthird-page.xhtml">
| <redirect/>
| <end-conversation />
| </page>
|
| </pageflow-definition>
In components.xml I included the new file:
| ...
| <component class="org.jboss.seam.core.Jbpm">
| <property name="processDefinitions">processdefinition.jpdl.xml</property>
| <property name="pageflowDefinitions">pageflow.jpdl.xml</property>
| <property name="pageflowDefinitions">pageflow2.jpdl.xml</property>
| </component>
| ...
|
Moreover I copied FlowBean.java, SimpleFlow.java and SimpleFlowAction.java to FlowBean2.java and so on. Of course SimpleFlowAction2.java looks like this:
| ...
| @Name("pageflow2")
| ...
| @Begin(pageflow="shellflow2")
| public void begin() {
| System.out.println("pageflow2: SHELLFLOW METHOD HIT!!!");
| }
|
| public String gotoFirstPage() {
| System.out.println("pageflow2: 1st page");
| return "first-page2";
| }
|
| public String gotoSecondPage() {
| System.out.println("pageflow2: 2nd page");
| return "second-page2";
| }
| ...
|
Now the secod pageflow works perfectly, but the first pageflow is broken:

(I shortened the stacktrace a little bit)
Did I screw up something? How can I get the first workflow get back to work again?
I suspect the components.xml, but I'm not sure. This must be the right place to define further pageflows which are defined in separate files, isn't it?
TIA for any suggestions.
