    Unexpected process end in the mid of a bpel

    stone_42 Jan 16, 2006 7:49 AM

      Hi,

      I wrote a simple process with the following bpel:

      <?xml version="1.0" encoding="UTF-8"?>
<process name="jbpmTestProcess" targetNamespace="urn:my:namespace"
 xmlns:tns="urn:my:namespace"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"

 <partnerLink name="defaultPLNK" partnerLinkType="tns:defaultPlnkT" myRole="service"/>
 </partnerLinks>

 <variables>
 <variable name="request1" messageType="tns:theMessage"/>
 <variable name="request2" messageType="tns:theMessage"/>
 <variable name="response1" messageType="tns:theMessage"/>
 <variable name="response2" messageType="tns:theMessage"/>

 </sequence>
</process>

      When I tried to execute the process, my client didn't get the second response and the last entries in the server's log were the following: 
      2006-01-16 13:42:24,890 DEBUG [org.jbpm.graph.def.GraphElement] event 'node-leave' on 'Assign(idass)' for 'Token(/normalFlow)'
2006-01-16 13:42:24,890 DEBUG [org.jbpm.graph.def.GraphElement] event 'transition' on 'Transition(4eba57)' for 'Token(/normalFlow)'
2006-01-16 13:42:24,890 DEBUG [org.jbpm.graph.def.GraphElement] event 'node-enter' on 'Assign(assign2)' for 'Token(/normalFlow)'
2006-01-16 13:42:24,953 DEBUG [org.jbpm.graph.def.GraphElement] event 'process-end' on 'BpelDefinition(jbpmTestProcess)' for 'Token(/)'

      This looks to me like a process termination right in the middle of the assign activity. The only reason for this I can imagine is that I read the variable 'request1' twice (once in assign "assign1" and once in assign "assign2"), but that makes no sense to me.
      What's the error I made?

      For better understanding, my wsdl: 
      <?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="urn:my:namespace"
 xmlns:tns="urn:my:namespace"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"

 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:bpel="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
 xmlns="http://schemas.xmlsoap.org/wsdl/">

 <bpel:property name="id" type="xsd:int"/>
 <bpel:propertyAlias propertyName="tns:id" messageType="tns:theMessage" part="id"/>

 <plt:partnerLinkType name="defaultPlnkT">
 <plt:role name="service">
 <plt:portType name="tns:jbpmTestProcessPT"/>
 </plt:role>
 </plt:partnerLinkType>

 <message name="theMessage">
 <part name="id" type="xsd:int"/>
 <part name="text" type="xsd:string"/>
 </message>

 <portType name="jbpmTestProcessPT">
 <operation name="init">
 <input message="tns:theMessage"/>
 <output message="tns:theMessage"/>
 </operation>
 <operation name="op2">
 <input message="tns:theMessage"/>
 <output message="tns:theMessage"/>
 </operation>
 </portType>
</definitions>

      Greetings,
      Martin
