Warning: Encountered 'this' keyword within closure

[Maria Jose Esteve]

This warning appears many times. Some examples:

"get": function():*{return this}
"get": function():* { return this._xmlArray[idx]; }
this.append(newValue);
(this['mapView'] as GoogleMapView).finishInitialization();

Would simply "[this]" be correct? (I have tested it in "([this]['mapView'] as 
GoogleMapView).finishInitialization();": it produces no error and the warning 
is gone)

Thx.
