Thanks for your reply.
I have searched the alloyui site more than once.
What i need is the datatable or the new Treeble.
The main problem is that alloyui has a lot of its own functions that break the yui3 code.
for example "datasource-io" has been replaces by "io", but this lacks some functions of yui3 datasource-io.
also the way alloyui handles json is slightly different from yui3 itself.
But, to be honest, alloyui has only some halfworking examples and if you try the yui3 examples within liferay most of them they won't work.
Firmi prego dentro per inbandierare questo come inadeguato.
