Hey there. You just have to put your wakeupOn-definition again to your processStimulus. .. perhaps there is another solution, but I do it like that and it's fine.
public void processStimulus(Enumeration criteria) { WakeupCriterion genericEvt; System.out.println("calling process stimulus"); while(criteria.hasMoreElements()) { genericEvt = (WakeupCriterion) criteria.nextElement(); if(genericEvt instanceof WakeupOnTransformChange) { System.out.println("hey great work !! it worked"); wakeupOn(changedTransform); } } } =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
