Hi,
I'm using jbpm 3.1.3,
I have a context variable that is a list, and I need to have a decision condition that evaluates by calling the contains() method on this list.
I'm trying :
<decision name="decision1" expression='#{MYLIST.contains("A") ? "a" : "b"}' >
However, this does not seem to work and throws an exception saying :
Caused by: org.jbpm.JbpmException: couldn't evaluate expression '#{MYLIST.contains("A") ? "a" : "b"}'
at org.jbpm.jpdl.el.impl.JbpmExpressionEvaluator.evaluate(JbpmExpressionEvaluator.java:38)
at org.jbpm.graph.node.Decision.execute(Decision.java:108)
... 57 more
Caused by: org.jbpm.jpdl.el.ELException: Encountered "(", expected one of ["}", ".", ">", "gt", "<", "lt", "==", "eq", "<=", "le", ">=", "ge", "!=", "ne", "[", "+", "-", "*", "/", "div", "%", "mod", "and", "&&", "or", "||", "?"]
Has anyone done this before ? Can the contains method be called inside an expression ? If not, are there any ways out ( i do not want to write a decision handler)
Also, can i use a script inside a decision handler to take a decision, and how can i do that ?
That is, can I say :
<script>
<variable name='MYLIST' access='read' />
<expression>
if(MYLIST.contains("A")) {
executionContext.leaveNode("a"); } else
if(MYLIST.contains("B")) {
executionContext.leaveNode("b"); } else {
executionContext.leaveNode("Other"); }
</expression>
</script>
inside a decision handler ? even this does not seem to work for me
