Where can I find documentation on "RichFaces" other method calls?
Some of them are documented in dev guide - components which where added later (fileUpload for example).
As I guess the best way is to explore ui.pack.js and framework.pack.js.jsf manually and find some useful methods there.
I don't know if documentation of js methods will be provided in future releases.
Maybe Nick or Ilya will tell us about future plans.
With best regards.
There is a alternate way to switch between the tabs by directly using java script,
you just have to call,
document.getElementById(<rendered tab id>_shifted).click();
here rendered tab id means the id which it get at render time like , form id+ : + tab id
