Hi, Welcome back! You are right and I have been returning boolean for example without any problems ... What I meant to say was that given:
<n:assign name="result" expr="myClassInContext.myStringMethod()"/> if myClassInContext.myStringMethod() returns null then you get something like: "ErrorReporter @ EXPRESSION_ERROR (java.lang.NullPointerException):" This is because of an exception in SCXMLSemanticsImpl#executeActions(): org.apache.commons.scxml.SCXMLExpressionException: java.lang.NullPointerException Thanks for looking at this.
