Bug on framset and embedded editor

I have an embedded edito inside a table which is inside a form. Then the form is opened on the right side of a two-framed frameset. AlsoI have an embedded view in the same form same table than the embedded editor the view and editor are doing linking when I try to switch

from one record to other in the view i get a NSD error. The problem is gone if I move the spanner form out of the frameset and open it in full mode.
