I noticed that drag & drop for Data View and Dynamic View Panel doesn't work here. While dragging e.g. the Data View Control from the controls panel into the layout panel show a + at the cursor position but when dropping nothing happens - no code nor element added ... so far these 2 controls are the only one that show this behaviour.
When I insert the correspondig tag (e.g. <xe:dataView id="dataView1"> ... ) in source the correct design element is shown in the layout panel ... strange).
I am using Domino Designer 8.53 Revision 20110916.0921
Not a showstopper :-) but maybe something that other are experiencing too.
