Unfortunatelly we can't support such old versions. latest GA which compatible with JSF 1.1 is RichFaces 3.1.6.
Thanks for the reply, ilya_shaikovsky
I downloaded that version and going to test it.
Now i am having a problem with an IBM component <hx:inputRowSelect>. Adding a <a4j:support> tag as a child to it. When the support event is triggered a full page refresh occurs! Actually, this is an old problem for me. It is here since a4j 1.1.1
Let me add a separate topic for this.
