[JAVA3D] Dynamic Behavior

[Risto Rangel-Kuoppa]

hello, I am trying to add a behavior under runtime to a transform group, for example, when I push a jButton in the AWT Form I would like an object to start rotating for 4 seconds, I have already done to rotate it when the application starts, but when I try to add the behavior in runtime an exception rises ... on the other hand, Instead of adding runtime behaviors, Can I restart a behavior? and How can I do that? ......... Does anyone could please help me? ... thank you very much ....
