I found one solution relate to my question.
This solution based on: node modified event, getData() method, Util classs.
It's a good solution, still if you another one, i am still listening.
Events are used to pass information back to listeners. What issues do you have with this approach?
First of all everything is working good for me now using this listeners.
You asked "What issues do you have with this approach?", my answer -
I wanted to be able to know which elements were added / modified or removed to a specific node. The change from 1.4.1 sp9 to 2.1.1GA solved for me the problem.
Still, there is something that i don't get. In this version there should be a way using the addCacheListener(Fqn, Object) to add a listener to a specific node in the cache as i understand. But, when doing so, i am getting an exception which this feature isn't yet implemented. Why?
Because it isn't implemented yet! :-)
Feel like implementing it and contributing it?
