[jboss-user] [JBoss Seam] - Calling a method from within code that has @CreateProcess do
I have a business process that is called from a method that is invoked from a pageflow. If
I add @CreateProcess to the method which is invoked from the pageflow the process starts
and variables are available on the page.
HOWEVER if I want to use the variables in the SLSB or POJO I cant seem to get access to
them. If I extract the creation of the new process then the process gets created but I
have to signal it and I dont have access to any of the processInstance or the token!
What's the SEAM way of doing so.
WHAT WORKS:
1) PageFlow has
< action expression="#{login.logmein}" / >
2) My POJO method is declared as
@CreateProcess(definition="asyncProcess")
public String logmein()
3) My variable is declared as
@Out(scope=ScopeType.BUSINESS_PROCESS)
public CustomerBean getCust() {
return cust;
}
4) My JSF has
< h:outputText value="#{login.cust.streetaddress}"/ >
5) Alternatively I could remove the @CreateProcess and write the following code where I do
have programatic access to the altered cust variable
org.jbpm.graph.exe.ProcessInstance pi =
JbpmConfiguration.getInstance().createJbpmContext().getGraphSession().findLatestProcessDefinition("asyncProcess").createProcessInstance();
Token token = pi.getRootToken();
pi.getContextInstance().setVariable("cust", cust);
token.signal();
CustomerBean cc = (CustomerBean) pi.getContextInstance().getVariable("cust");
But that does not seem like the SEAM way of doing things.
WHAT DOES NOT WORK:
1) If I extract the code that calls @CreateProcess to a separate method the jbpm process
"acts" like a async process and needs a signal to start
public String logmein()
{
createSyncProcess();
}
@CreateProcess(definition="asyncProcess")
private createSyncProcess() {
}
In this case the pageflow continues, old values are shown on the page and process never
kicksoff!
Any info would be appreciated.
