RJS calls being ignored

I have a controller with page.call calls to my javascript functions. That normally works just fine. However, on one of our servers the page calls are being totally ignored. Same code but it works on most but not on one. It is not a production/development issue as it works on the 32-bit production server and not on the 64-bit production server.

Everything else works just fine, but the page.call and page.alert calls just don't do anything. No javascript errors (javascript is on and is working), nothing in the log file, nothing. The calls are just ignored.

So...

Is there a setting to turn RJS on and off? If so, how?

BTW: Here is the code from the controller:

  def showoccupied     @spaces = Space.get_spaces($current_drawing)

    render(:update) do |page|       page.alert('Show Occupied')       page.call 'ClearAllPanes'       page.call 'ClickDetailed'        page.call 'InitLayers'        page.call 'ClearInternalList'       page.call 'DefineSpacetypeKey'       @spaces.each {|space|                   RAILS_DEFAULT_LOGGER.info space.unq_space_id       if (space.occup_type_cd == "OCC")         page.call 'AddToInternalListRgb', space.unq_space_id, 0, 255, 0       elsif (space.occup_type_cd == "VNCT")         page.call 'AddToInternalListRgb', space.unq_space_id, 255, 0, 0       elsif (space.occup_type_cd == "NAPP")         page.call 'AddToInternalListRgb', space.unq_space_id, 255, 255, 0       elsif (space.occup_type_cd == "DEFT")         page.call 'AddToInternalListRgb', space.unq_space_id, 0, 255, 255       else         page.call 'AddToInternalListRgb', space.unq_space_id, 255, 0, 255       end       }     page.call 'HighlightInternalList', -1   end   end

The expected output is made to the logger, so I know the entire process is run to completion, but none of the page calls do anything on this server.
