Data source does not update after making changes in a form

on an xpage I selected a form as data source (a form in the same database) when I noticed only one field showed up.

It seemed that the form had a lot of computed subforms so there where actually little fields on the form.

Therefor I updated the form so most computed subforms are not being used anymore.

The problem is that whenever I remove and add the form again as data source no changes are noticable.

How must I solve this?

do you still see the same result if you close and reopen Designer? It sounds like we may be over-efficient…
