I already found out how...
...
String[] expandedPath = {"0"};
treeState = new TreeStateBase();
treeState.setTransient(true);
//Expand the tree´s first level nodes
treeState.expandPath(expandedPath);
treeModel.setTreeState(treeState);
...
By passing out the root index in the expanded path array to the treeState
object.

JV

Didn´t know that. It now works fine. Thanks a lot.
One last question: ¿How can I open the tree´s first level when it gets
painted for the first time?

The new versions of tomahawk now use hard coded strings with the
property names. So there is no need for a facelets workaround anymore,
just use the raw component (no component handler or attribute renaming
needed)
