Could someone give me an advice what I'm doing wrong at process definition? Constraint definition looks like below:     <sequenceFlow id="_5-_4" sourceRef="_5" targetRef="_4" name="constraint" tns:priority="1" >       <conditionExpression xsi:type="tFormalExpression" language="http://www.java.com/java" >return company==null;</conditionExpression>     </sequenceFlow> I also tried with casting:       return (com.tl.module_visitor.transferobject.VisitorCompanyTO)company==null; but still get the same error. I have import section:     <extensionElements>      <tns:import name="com.tl.module_visitor.transferobject.VisitorCompanyTO" />     </extensionElements> item definition:      <itemDefinition id="_companyItem" structureRef="VisitorCompanyTO" /> process variable is defined:     <!-- process variables -->     <property id="company" itemSubjectRef="_companyItem"/> What can be reason for this problem? Thanks in advance, Tadeusz. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779315#779315] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
