Hello,

What is tree switchType?

[oyesiji77]

what do you mean by switchType

[nbelaevski]

Value of rich:tree "switchType" attribute

[oyesiji77]

The value of the switchType is client

[nbelaevski]

Tree is not interacting with the server in this switchType. If you submit form externally, you'll see listeners firing.
