Hi, I'm new in this Community;

We have a huge project with richfaces 3.3.x / JSF 1.2 / Tomcat > 6

Now we would like to migrate to RF4 / JSF 2.0

BUT there are several problems on migrating to RF4

i.e.:

TreeState class is missing

<rich:tree componentState="#{class.xxx}"/>

DataScrollerEvent

<rich:datascroller actionListener="xxx" ... />

has anybody resolved this issues ?
