Hi Oscar;

  You are 100% correct! The DW Painter's EditMask based columns (check box or Radio Button) do not have a "required" property setting. To make measures worse, setting the "required" property under PowerScript control - for example: DC.Modify (".EditMask.Required=Yes") - makes it work but also destroy's the current "mask" setting (which I did not expect). Then of course, you have the PS issue side of all of this as well.

  My suggestion would be to create a Support Ticket for this EditMask "required" feature issues. At least that way, we can get this problem logged and over to Engineering.

  As a workaround, you could:

1) Have your own PowerScript check just these required EditMask columnsby performing a GetItemXxxxx() or GetText() just before the Update() command.

2) Create a mirror DWO with no edit masks. Then set all the necessary columns to "required". Instantiate the new DWO in a DataStore. Before the Update(), copy the current DWO's primary buffer to the DS DWO's primary buffer and then perform a FindRequired() on the DS's DWO.

  I think that option #1 or #2 will also work for the PowerServer Apps as well.
