Hi All,
Not sure whether my previous message has been sent correctly,
apologize if you have seen this message,
I don't think the previous one went out.
Jess reported an error in routine DefinstanceList.definstance
while executing (definstance opt ?a dynamic).
Message: Obj doesn't accept PropertyChangeListeners.
Program text: ( definstance opt ?a dynamic ) at line 7.
Nested exception is:
TestBean.addPropertyChangeListener(java.beans.PropertyChangeListener
Jess is telling you that to use a dynamic definstance, your Bean has
to have a "public void addPropertyChangeListener
(PropertyChangeListener)" method, but your class doesn't seem to have
such a method.
