Hi
I created a process in camunda modeler and tested that in camunda engine and every thing was ok .
I wrote a unit test for that bpmn and every thing was ok again.
Until the process reaches to specific script task which that has this script :
def users= number.split(',') as Set
execution.setVariable("selectedUsers", users)
script type is groovy .
when process reaches to that script task , an error occurs .
error is :
org.camunda.bpm.engine.ScriptEvaluationException: Unable to evaluate script while executing activity 'scriptTask' in the process definition with id 'testProcess:1:3': groovy.lang.MissingMethodException: No signature of method: [Ljava.lang.String;.split() is applicable for argument types: (java.lang.String) values: [,]
Possible solutions: split(groovy.lang.Closure), wait(), init(), sort(), toList(), tail()
