[rules-users] Is there any limitation about the length of attribute's name when declare type in drl file

Hi all,Is there any limitation about the length of attribute's name when declare type in drl file? I encountered a problem these days, I declared a new type in rule file, when fire rules, it always throw java.lang.ClassCaseException: test.obj cannot be cast to test.obj. As I inspected, this is caused by the length of an attribute's name is too long, it's 35 characters, if I remove this attribute, there's no exception. Following is snippet of my rule file: package testdeclare obj@propertyReactivetype : Stringname : Stringattribute_name_too_long_reach_limitation: Booleanendrule "a"dialect "mvel"salience 0no-loopwhen$obj:obj(type == "a")thenmodify ($obj) {name = "abc"};end -- View this message in context: http://drools.46999.n3.nabble.com/Is-there-any-limitation-about-the-lengt...
