How is the correct way to build Master-Detail Forms

Hello

I'm trying to create a master-detail form, and I'm not sure, how to do it
correctly.

What I like to do is, that the related master field in the detail is not
showed. In Oracle Forms (always my reference ;-) ), you had to put it onto
page 0. 
What I did is, that I made it invisible, and the text I changed in the
layout to lenght and height 0. After this operation, the designer is is
confused, and shows me the objects in the object navigator wrong (e.g.
twice).

How is the proper way to handle that?

Regards

Dieter

PS:	Are you interested to have comments about errors in the XP world of
GNUe?
	E.g. that the scrollbar disapears in the property inspector when you

	click on another item in the object navigator
