> If we have a grid with a t:add property and a mixin that on SetupRender gets
> the sortModel and applies sorting, then on the grids SetupRender we get a
> RuntimeException "Bean editor model for %s already contains a property model
> for property '%s'.".
> This happens because on grid line 510 we set the previous dataModel to null
> and recreate it.When the model is about to be created again we try to add the
> extra properties again with BeanModelUtils.modify resulting to the exception
> mentioned above
