Proposed solution\r\n\r\nMy suggestion is to accept {{undefined}} as a valid value, but instead of actually setting it, use it to trigger removing the property.\r\n\r\nThat way, for that specific window I can set {{modal}} to {{undefined}} which would remove that property from the dictionary passed to {{Ti.UI.createWindow}}.",
