<f:view>

The jsp page flow works just fine when I dont includ the menu_incl.jsp.

why is the component tree already building ??? I would appreciate if some one could explain this weird behaviour.

It could occurs if your binding bean - session scoped.

and there is nothing about RF b.t.w.

[rajeshiv]

I came around this errror by assigning component ids for all the JSF and richfaces components in my jsp!!! Let me know if there is an alter solution to this.
