"[EMAIL PROTECTED]" wrote : Have your start-node transition directly to a

to inject the actual process instance somewhere and signal it.
That's what I am doing but the change described above seems to break the
correct behavior.
Here's how my pageflow starts:
| <pageflow-definition
| name="PaymentAuthorization">
| <start-state name="start">
| <transition to="selectSource">
| <action expression="#{sourceManager.selectSource}"/>
| </transition>
| </start-state>
|
| <decision name="selectSource" expression="#{sourceManager.result}">
| <transition name="abort" to="menu"></transition>
| <transition name="proceed" to="requestPin"></transition>
| <transition name="chooseSource" to="chooseSource"></transition>
| </decision>
|
If the pageflow is started from this method via a POST it works:
| @Begin(pageflow="PaymentAuthorization")
| public void start() {
| }
|
However, if I started via a GET (calling the above method via pages.xml) or via
a method anneotated like this:
| @Begin(ifOutcome="proceed", pageflow="PaymentAuthorization")
| public String initiate() {
| ...
| }
|
then I get the following:java.lang.ClassCastException:
org.jbpm.graph.node.StartState
| at org.jboss.seam.core.Pageflow.getPage(Pageflow.java:129)
| ...
which seems to be a direct result of the change described above, since the
start node is forced to cast to a Page, which of course fails if it is a
<start-state> instead.
Any ideas on how to start with a decision when forced to start with a page?
