Hello all,
I try to develop an exemple of multiple users for ending a process
I want to start a process
doing step1 by toto
doing step2 by titi
ending process with tata
Here its my current code :
processDefinition.xml
<process-definition xmlns="urn:jbpm.org:jpdl-3.2"
name="simple">
<start-state name="start">
<transition name="toStep1" to="step1" />
</start-state>
<task-node name="step1">
<task name="step1">
<assignment actor-id="toto" />
</task>
<transition name="toStep2" to="step2" />
<transition name="cancel" to="error" />
</task-node>
<task-node name="step2">
<task name="step2">
<assignment actor-id="titi" />
</task>
<transition name="toStep3" to="step3" />
<transition name="cancel" to="error" />
</task-node>
<task-node name="step3">
<task name="step3">
<assignment actor-id="tata" />
</task>
<transition name="toEnd" to="end" />
<transition name="cancel" to="error" />
</task-node>
<end-state name="error"/>
<end-state name="end" />
</process-definition>
My page is the fallowing WorkFlow.xhtml
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"

template="include/template.xhtml">
<ui:define name="body">
<ui:include src="/include/menu.xhtml" />
<h1><h:outputText

<h:form>
<div>
<h:outputText value="There are no process started for the
moment" rendered="#{empty taskInstancePriorityList}"/>
<a4j:repeat value="#{taskInstancePriorityList}"
var="task" rendered="#{not empty taskInstancePriorityList}">
<h:outputText value="Process created by #{actor.id} at
#{task.taskMgmtInstance.processInstance.start}"/>
<br/><h:outputText styleClass="ml30"
value="STATUS : #{task.name} Progress :
#{orderStock.getPercent(task.name)}"/>
<br/><s:button styleClass="ml30"
action="#{orderStock.doStep1}" taskInstance="#{task}"
value="DoStep1"/>
<s:button styleClass="ml30"
action="#{orderStock.doStep2}" taskInstance="#{task}"
value="DoStep2"/>
<s:button styleClass="ml30"
action="#{orderStock.doEnd}" taskInstance="#{task}"
value="DoEnd"/>
<s:button styleClass="ml30"
action="#{orderStock.cancel}" taskInstance="#{task}"
value="Cancel"/>
<br/><br/>
</a4j:repeat>
</div>
<br/><br/>
<h:commandButton value="Start Process"
action="#{orderStock.startProcess}"/>
</h:form>
</ui:define>
</ui:composition>
And OrderStock.java looks like this :
package com.ste.crw.jbpm;
import java.io.Serializable;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.bpm.BeginTask;
import org.jboss.seam.annotations.bpm.CreateProcess;
import org.jboss.seam.annotations.bpm.EndTask;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
@Name("orderStock")
@Scope(ScopeType.BUSINESS_PROCESS)
public class OrderStock implements Serializable{
private static final long serialVersionUID = -6823728442889976233L;
public String getPercent(String name){
if(name.equals("step1")){
return "0%";
}else if(name.equals("step2")){
return "33%";
}else if(name.equals("step3")){
return "66%";
}else{
return "100%";
}
}
@CreateProcess(definition="simple")
public void startProcess(){
}
@BeginTask
@EndTask(transition="toStep2")
public void doStep1(){}
@BeginTask
@EndTask(transition="toStep3")
public void doStep2(){}
@BeginTask
@EndTask(transition="toEnd")
public void doEnd(){}
@BeginTask
@EndTask(transition="cancel")
public void cancel(){}
}
The beginning works fine
I Create the process , and when i'm log on website with login "toto", I see
the process
but when i push on "DoStep1" button i have the following error :
javax.el.ELException: java.lang.IllegalStateException: begin method invoked from a
long-running conversation, try using @Begin(joi
n=true) on method: doStep1
Where is the problem ?
I'm a begginner with JBPM and Seam , and documentation is not easy to understand
I use : JBPM 3.2.7 and Seam 2.1.2
Thanks in advance for your help
Leod
