A tool which would listen for the context change does not exist.
But you can execute java code when using a tool either using java
services [1] or with external java action [2].

Hi Laurent,
Thank for your answer.
I know how to use the External Java Action and I want to call it when the context of element changes. But my issue here is that I don't know when the context of element changes, because there are many ways to change the context of container, such as adding/ removing sub-Node, changing name of container, or editing sub-Node ...
Could you please guide me how to implement the listener for these actions?
Best Regards,
Tuan Hoang
