[Florent Legendre (JIRA)]

Missing elements in jpdl-4.3.xsd
--------------------------------

                 Key: JBPM-2715
                 URL: https://jira.jboss.org/jira/browse/JBPM-2715
             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: Florent Legendre
            Priority: Critical


The xsd file for the jpdl has created validation errors in 4.0, 4.1, 4.2 and now also 4.3, but the difference is that the parsing of the jpdl has become more efficient in 4.3 and now throws an exception when defining an argument on a constructor element. 

The main problem here is that the declaration of arg elements does not allow for any child, which means that you can define the type of the argument, but not its value, making it pretty useless.

Here are the extracts of the various problematic files:

jpdl-4.3.xsd (from line 921):
==========
 <complexType name="argType">
    <annotation><documentation>The method arguments.
    Each 'arg' element should have exactly one child element 
    that represents the value of the argument.
    </documentation></annotation>
    <attribute name="type" type="string">
      <annotation><documentation>The java class name representing 
      the type of the method.  This is optional and can be used to 
      indicate the appropriate method in case of method overloading. 
      </documentation></annotation>
    </attribute>
  </complexType>

An example jpdl which would trigger the error (as the string element in the arg does is not valid based on the xsd):
=========================================================================================
<?xml version="1.0" encoding="UTF-8"?>

<process name="MyProsess"
         version="1"
         xmlns="http://jbpm.org/4.3/jpdl">

    <start name="start">
        <transition name="myTransition"
                    to="end">
            <event-listener class="com.comp.MyEventListener">
                <field name="myObjectField">
                    <object class="com.comp.MyObjectField">
                        <constructor>
                            <arg type="java.lang.String"><string value="hello world"/></arg>
                        </constructor>
                   </object>
                </field>
            </event-listener>
        </transition>
    </start>

    <end  name="end"/>
</process>
