Layout Editor: Saving region properties not working

[maurofmferrao]

Trying to save a region for a Widget ( or a Zone ) fails with the following message: The Region dimensions cannot be empty or negative

Steps to replicate:

• Add a Widget like a Video and double click in viewer ( or use context menu Options )
• Change name or Loop and check that it doesn't save and shows the error message in the form
• Add a zone from the Template Editor and check that it does the same behaviour
