Revision 1867585

Fixed: Error in log when looking for parties at partymgr/control/main
(OFBIZ-11201)

These are similar issues in Minilang than the one fixed initially for
<set field="userLoginSize" value="${util:size(logins)}" type="Integer"/>
Fixed by replacing by 
<set field="userLoginSize" value="${groovy:logins.size()}"/>
