[Laszlo-user] initstage="defer" not working as supposed

[Daniel Garrido]

You're right Robert.

I just added a dummy subnode and the initstage="defer" worked.  Could
never have guessed that :S
I really appreciate your help, but I feel very insecure using this
framework, cause I'm mostly depending on your help to move forward.

Anyway thanks a lot for your help. Laszlo should be very grateful to you.

Regards,
Daniel
