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...
