Yael,
Your problem is that a Pmw.EntryField is itself a compound widget
(I've been caught by this one too). You want something like:

dialog.configure( activatecommand = w.component("entry").focus_set )

You can also get a similar result by replacing

dialog.configure( activatecommand = w.focus_set )
dialog.focus_force()

with

w.component("entry").focus_force()
