I did not try LoadComponentFromURL against the forms container to see if that
changed also.

To reproduce load the attached file, with macro execution enabled.
On the main form
  Select any item in the grid
  Select Article in the drop down list
  Click 'Edit as' button.
  Close the form and save the record.

This code is run:

sub updateBiblio
	dim bkMark as variant
	dim oForm as object
	dim ResultSet as object
		
	thisDatabaseDocument.LockControllers
	oForm = thisDatabaseDocument.FormDocuments.getByHierarchicalName( "Biblio" ).open
	if not isEmpty( oForm ) then
		'xray oForm
		ResultSet = oForm.Drawpage.Forms.getbyIndex( 0 )
		bkMark = ResultSet.getBookMark
		Resultset.Reload
		do while NOT ResultSet.isLoaded
			wait 1
		loop
		ResultSet.moveToBookmark( bkMark )
	end if
	thisDatabaseDocument.UnLockControllers
		
end sub

xray oForm returns NULL OBJECT ??
