List.toString() not parsable
----------------------------

                 Key: IMPERIUS-25
                 URL: https://issues.apache.org/jira/browse/IMPERIUS-25
             Project: Imperius
          Issue Type: Bug
            Reporter: David Wood
            Assignee: Bill Stoddard


If I use the following policy:

Import Class java.util.List:list1;
Strategy Execute_All_Applicable;
Policy 
{
	Condition 
	{  
	   list1.toString() == "something"
	}
	Decision 
	{   
		list1.toString()
	}
}:1;

I get 

 Symbol does not exist list1.toString
<AST>:0:0: unexpected end of subtree
Did NOT parse!

	at
com.ibm.watson.pml.spl.policy.SPLPolicyParser.parse(SPLPolicyParser.java:39)
	... 1 more


However, if I change the list1 to a type Properties then the problem goes
away.


Import Class java.util.Properties:list1;
Strategy Execute_All_Applicable;
Policy 
{
	Condition 
	{  
	   list1.toString() == "something"
	}
	Decision 
	{   
		list1.toString()
	}
}:1;
