Problem modeling custom portal site

Hi guys,

I am trying to create a custom portal site, but I have big problems using the palette properties. I want a page with 4 taps, by clicking each getting the interface of a webservice. I used “Select-Ones Tabs” and created 4 options, but I can not assign the webservice interfaces to the individual options. Is there another easier way to create that kind of page? I mean, it is that easy to drag&drop the webservice connector to a form. Why not assigning a form to the options or to the tab property.

Ah, by the way, all my properties in a form are positioned automatically consecutively. Is there any posibility to positioning them free?

Thanks a lot for your support.
