I am not sure whether this will help or not but is it possible that the underlying cause of the problem is that you are generating the map in the controller? A map is after all a view on some data so arguably should be generated in the view. If in the controller you just setup whatever variables are required to define the map parameters, markers and so on, and move the map generation to the view (with actual code in the model or helpers of course) things might work out easier. In the particular case you mention the controller would just need to define that maps 1 and 53 should be shown and the view would show them.
