Description

Provide a means to "unset" positioning properties for a view so that layout behavior goes back to the default behavior IE:

view.left = 10; 

/// stuff happens and now you want to revert to default positioning for the element
view.left = ?;

I would prefer "view.left = undefined" or "view.left = null". The reason for that lies in the fact that people will try to do same thing on other (Titianium JS host) objects that might blow things up.

These will work too after the fix will be pushed: view.left = undefined; view.left = null;

Cool, thanks. :)

Test code (already works on iOS and MobileWeb)

   var win=Ti.UI.createWindow({
   backgroundColor : 'blue'
   });
    
   var view=Ti.UI.createView({
   width: 500,
   height: 300,
   top: 10,
   bottom: 10,
   left: 0,
   backgroundColor: 'red'
   });
    
    
   win.add(view);
   win.open();
   
   setTimeout(function() {view.top=undefined;}, 2000);
