Hi,

What is the actual reason for this error? Why cant drools give some better explaination of this problem when the exception is thrown.

Here is the snippet of my code:

workingMemory.setGlobal("validationErrorHierarchy", validationErrorHierarchy);   //workingMemory is StatefulKnowledgeSession

I am using the following variable in  dslr:

global com.model.ValidationErrorHierarchy validationErrorHierarchy;

thanks
