[Users] Porting from GeoExt1 to GeoExt2

[Riccardo Gaeta]

Hi all,
I have some problem to get all my code from previous version 1 of GeoExt to
v2.
While scripting, I've discovered that the plugins
"GeoExt.plugins.TreeNodeRadioButton" does not exist anymore: is it right?
How could be possible than to decide which layer must be "active" and which
not?
Was a really useful function for me indeed.

Thanks very much to point me toward some solution.
