[jboss-user] [jBPM] - Process in Eclipse Designer with two Script Tasks

Kai Gebhardt [https://community.jboss.org/people/kg86] created the discussion "Process in Eclipse Designer with two Script Tasks" To view the discussion, visit: https://community.jboss.org/message/717907#717907 -------------------------------------------------------------- Hi, I tried to create a process in the eclipse designer. I created a global process variable 'anzahl' as Integer. Then I created two script tasks. The first set 'anzahl' as 20. The second print the value of 'anzahl'. But the result is 'null' and not '20' as I expected. Here is my XML Code of process: <?xml version="1.0" encoding="UTF-8"?> <definitions id="Definition"              targetNamespace=" http://www.jboss.org/drools http://www.jboss.org/drools"              typeLanguage=" http://www.java.com/javaTypes http://www.java.com/javaTypes"              expressionLanguage=" http://www.mvel.org/2.0 http://www.mvel.org/2.0"              xmlns=" http://www.omg.org/spec/BPMN/20100524/MODEL http://www.omg.org/spec/BPMN/20100524/MODEL"              xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"              xsi:schemaLocation=" http://www.omg.org/spec/BPMN/20100524/MODEL http://www.omg.org/spec/BPMN/20100524/MODEL BPMN20.xsd"              xmlns:g=" http://www.jboss.org/drools/flow/gpd http://www.jboss.org/drools/flow/gpd"              xmlns:bpmndi=" http://www.omg.org/spec/BPMN/20100524/DI http://www.omg.org/spec/BPMN/20100524/DI"              xmlns:dc=" http://www.omg.org/spec/DD/20100524/DC http://www.omg.org/spec/DD/20100524/DC"              xmlns:di=" http://www.omg.org/spec/DD/20100524/DI http://www.omg.org/spec/DD/20100524/DI"              xmlns:tns=" http://www.jboss.org/drools http://www.jboss.org/drools">   <itemDefinition id="_anzahlItem" structureRef="Integer" />   <process processType="Private" isExecutable="true" id="com.sample.bpmn.anzahl" name="Anzahltest" >     <!-- process variables -->     <property id="anzahl" itemSubjectRef="_anzahlItem"/>     <!-- nodes -->     <startEvent id="_1" name="StartProcess" />     <endEvent id="_3" name="EndProcess" >         <terminateEventDefinition/>     </endEvent>     <scriptTask id="_5" name="Anzahl ausgeben" scriptFormat=" http://www.java.com/java http://www.java.com/java" >       <script>System.out.println(anzahl);</script>     </scriptTask>     <scriptTask id="_6" name="Anzahl 20" scriptFormat=" http://www.java.com/java http://www.java.com/java" >       <script>anzahl= 20;</script>     </scriptTask>     <!-- connections -->     <sequenceFlow id="_5-_3" sourceRef="_5" targetRef="_3" />     <sequenceFlow id="_6-_5" sourceRef="_6" targetRef="_5" />     <sequenceFlow id="_1-_6" sourceRef="_1" targetRef="_6" />   </process>   <bpmndi:BPMNDiagram>     <bpmndi:BPMNPlane bpmnElement="com.sample.bpmn.anzahl" >       <bpmndi:BPMNShape bpmnElement="_1" >         <dc:Bounds x="16" y="16" width="48" height="48" />       </bpmndi:BPMNShape>       <bpmndi:BPMNShape bpmnElement="_3" >         <dc:Bounds x="382" y="17" width="48" height="48" />       </bpmndi:BPMNShape>       <bpmndi:BPMNShape bpmnElement="_5" >         <dc:Bounds x="222" y="15" width="125" height="48" />       </bpmndi:BPMNShape>       <bpmndi:BPMNShape bpmnElement="_6" >         <dc:Bounds x="100" y="15" width="80" height="48" />       </bpmndi:BPMNShape>       <bpmndi:BPMNEdge bpmnElement="_5-_3" >         <di:waypoint x="284" y="39" />         <di:waypoint x="406" y="41" />       </bpmndi:BPMNEdge>       <bpmndi:BPMNEdge bpmnElement="_6-_5" >         <di:waypoint x="140" y="39" />         <di:waypoint x="284" y="39" />       </bpmndi:BPMNEdge>       <bpmndi:BPMNEdge bpmnElement="_1-_6" >         <di:waypoint x="40" y="40" />         <di:waypoint x="140" y="39" />       </bpmndi:BPMNEdge>     </bpmndi:BPMNPlane>   </bpmndi:BPMNDiagram> </definitions> Have I made some mistakes?
