"org.jbpm.pvm.internal.wire.WireException: couldn't initialize object 'null': couldn't find property setter setXXX for value true" for native boolean setters ------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBPM-2717 URL: https://jira.jboss.org/jira/browse/JBPM-2717 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: jBPM 4.3 Environment: Windows Vista, java 1.6, jboss 4.2.2.GA Reporter: Per Christian Henden Assignee: Huisheng Xu Attachments: booleanPropertyBugTest.diff, JBPM-2717.patch I ran into a problem with accessing boolean properties of an eventListener. I've attached a patch to trunk of ./modules/pvm/src/test/java/org/jbpm/pvm/internal/wire/ObjectWireTest.java that adds a test that exposes this problem. Basically, the example below fails with the error "org.jbpm.pvm.internal.wire.WireException: couldn't initialize object 'null': couldn't find property setter setCreateXml for value true" JPDL-fragment: <event-listener expr="#{stateApprovalAction}"> <property name="createXml"> <true/> </property> </event-listener> Java-fragment: public void setCreateXml(boolean createXml) { this.createXml = createXml; } Workaround: changing the Java-side to use a Boolean instead of a boolean for the method parameter. While there is a workaround, I will still suggest supporting both Boolean and boolean-based setters.
