I have included a solution, where my problem occurs.
First: create (in form: planning) 3 records. One with status: 1
one with status: 2 and one with status:3
If you go to the form: planning-overview you see three portals with, each portal, one record.
Now change the status-field (in portal 3 at the bottom) from 3 to 1.
If you click out of the field, you see that the record moves to the first portal, this is good.
But the record stays in portal 3 too! This is wrong!
If you go the designer-mode and back to browse-mode everything is fine again.
Can this be fixed?
