[Closed] on attachedToNode do… bug?

when I try to clone my scripted modifier it won’t acknowledge the original modifier. Am I doing something wrong?

   on attachedToNode orig do ( -- this function doesn't work when a group is cloned?
 		print "plugin modifier jpaligner:attachedToNode called"
 		print this.jpaMatIDlist
 		print orig
 	)

returns this result:

"plugin modifier jpaligner:attachedToNode called"
 jpaligner:JPA Attribute Holder
 undefined
