getVariableData function does not return the actual value even for simple typed variables
-----------------------------------------------------------------------------------------

                 Key: BPEL-301
                 URL: https://jira.jboss.org/jira/browse/BPEL-301
             Project: JBoss jBPM BPEL
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Engine
    Affects Versions: jBPM BPEL 1.1 GA
            Reporter: Jay Yan
            Assignee: Alejandro Guizar


According to BPEL 1.1 Spec, the function getVariableData should behave in this way:

"When only the first argument is present, the function extracts the value of the variable, which in this case must be defined using an XML Schema simple type or element. Otherwise, the return value of this function is a node set containing the single node..."

However, even when a variable is defined using a simple type such as type="xsd:int", getVariableData () call on that variable still return the node instead of the numeric value. As the result, array[getVariableData(var)] does not work, while array[position()=getVariableData(var)] and array[number(getVariableData(var))] both work.
