Hi,
I tried that function, but it doesn't seem to exist on the
jess.ReflectFunctions class (I am using 7.0 beta 4. There seems to be a a
"static Value a(Class, Object) throws JessException" method based on browsing
the class file. Could this be it?
Also, in regards to the original question, just thought about something.
Since returning "new Value(Boolean())" from my userfunction returns the Java
Object, I'm still not clear about why this didn't work:
(test (eq (ognl-get ?obj "booleanProperty") (Boolean.TRUE)))
shouldn't 'eq' call returnedObj.equals(Boolean.TRUE) ?
