You may just use rich:tree component with ajaxSubmitSelection enabled to implement the behaviour you need.
so the receiving component does then automatically receive the data?
Thx btw. ( I am still searching for light in the big fog of JSF :) )
nodeSelectListener will be called after selection event fire the ajax request to server. So you can manage your data according your needs.
thx a lot.
I will try that.
BTW: you have very good response times here !! Keep up the work, i really love whats going on here !
