oooops, I'm very sorry: I just scrolled down the example in http://livedemo.exadel.com/richfaces-demo/richfaces/tree.jsf;jsessionid=D943135D03EF7657DCD524DA12707DCD?c=tree
and saw, that there is actually the source-code for the model there too - sorry for complaining, this is exactly what I was looking for.
Actually i am agree with your previous complains .
Examples in livedemo/exadel.com are not sufficient also Java classes(backing beans) are missing for that of usage other than default tree model.
i can't find any running example for usage of tags below:
Actually these tags make it interesting for me to use rich:tree
I hope, i will find some running examples, and will too declare my complains off .
