Prevent saving the resource when using guvnorEditorObjRef, in case if validation fails.

by worldofprasanna

Hi All, We have embedded the Guvnor decision table asset into our html page and obtained the guvnorEditorObjRef to validate the new rule which is added. We wrote our business logic within the function, guvnorEditorObjRef.registerBeforeSaveAllButtonCallbackFunction() And it works fine. But the problem is when we find the business validation got failed, we couldn t stop the resource from saving. Check In dialog box opens and we couldn t find a way to prevent it from saving. Is there anyway to prevent the asset from Saving in case, if the validation failed ? Thanks, Prasanna Venkataraman. -- View this message in context: http://drools.46999.n3.nabble.com/Prevent-saving-the-resource-when-using-...

NullPointerException while loading pkg by KnowledgeAgent

by FlyingEagle

Hello, I have this exception in my Drools application and I don't know what's happening. I try to load a pkg by applying a defined change set by the KnowledgeAgent. If I load the pkg by the KnowledgeBuilder, everything is fine, but I want to use the KnowledgeAgent, so that changes are automatically recognized. Can anybody help me?

by bharadwaj2012

This usually indicates incompatible versions of two libraries. Get the most up-to-date jars of drools and try again. Also make sure you don't have multiple versions on the classpath -- View this message in context: http://drools.46999.n3.nabble.com/Hi-people-im-a-drools-newbie-i-get-this...
