8:30 p.m.
The following block of code inside org.drools.base.ClassFieldReader is throwing an
exception and I don't quite understand why. Can anyone advise? Thanks in advance.
public int getIntValue(InternalWorkingMemory workingMemory,
final Object object) {
return this.reader.getIntValue( workingMemory,
object );
}
Object is of type Long, with value = 0, when the throw happens, and workingMemory is null
(having been explicitly passed in as null by the method two layers up in the stack:
public boolean isAllowed(final InternalReadAccessor readAccessor,
final InternalFactHandle handle,
final InternalWorkingMemory workingMemoiry,
final ContextEntry context) {
return this.evaluator.evaluate( null,
this.readAccessor,
handle.getObject(),
this.field );
}
While sitting on the breakpoint in getIntValue, the live call stack is as follows:
