Re: [rules-users] NullPointerException with factType.get(fact, "fieldname")

Manstis was right, I was trying to access Java class with the API for accessing declared (DRL) types. ValidationError class was created with Drools Workbench data modeller. I thought that data modeller creates declarative classes, like in Drools Guvnor. I imported ValidationError as normal Java class and and started to use as it as normal Java class and problem was solved. Sorry for all the trouble and thanks for help! -Jarkko -- View this message in context: http://drools.46999.n3.nabble.com/NullPointerException-with-factType-get-...
