[BUGFIX] Fix Drag+Drop in Page Module in Workspaces

When using Drag+Drop in Page Module a different
functionality is used than using Clipboard (Move+Paste)
while moving a record in the page module.

This results in a different behaviour when dealing in Workspaces.

The patch uses the same "cmd" instead of "data"
for DataHandler now for Drag+Drop than in Clipboard.
