I have developed a workflow extension , which returns arrayList as OUT-PARAM , invoking the extension is successful even I am able to get the arrayList data in WF env. After the completion of the extesnion , i.e when it terminates exception is thrown.
I am passing the accountList to java extension class as List Of accounts:
var acctList = new java.util.ArrayList();
acctList.add(acctObj.getJavaObject());
acctList.add(acctObj.getJavaObject());
accountList.set(acctList);
accountList refers to relevant data object which is of type list .
the O/p param is mapped to relavnt data which is of type 'List'
