javascript - 多层OpenLayers SelectFeature

我正在使用LayerSwitcher向OpenLayers映射中添加几个KML层（88）。我已经将所有图层添加到SelectFeature控件中。但是，一旦使用OpenLayers.Map.addLayers在地图上添加了77个以上的图层，就永远不会调用SelectFeature的onSelect函数。

它似乎与KML层无关，因为我可以从addLayers调用中删除任何11个层，其余层都可以正常工作。注意：我不必从SelectFeature构造函数中删除任何内容。

proprietaryMap.addLayers(
[
  BaseLayer,
  SectionLayer, DistrictLayer, BoroughLayer,
  Business, Hotel, Market, Restaurant,
  Library, Museum, Theater,
  PostSecondary, PrivateEarly, PrivateElementry, PrivateHigh, PrivateJunior, PrivateK8, PrivateK12,
  PublicElementry, PublicHigh, PublicJunior, PublicK8, PublicK12, PublicBuilding, PublicSecondary,
  Consulate, Court, Embassy, GOffice, Military, PostOffice,
  Hospital, Inpatient, Outpatient,
  Corrections, Battalion, Division, Engine, Special,
  CCB, Checkpoint, Precinct, NOther,
  Amusement, Beach, Botanical, Garden, Golf, Park, Playground, RecCenter, Sports, Zoo,

  Airport, Bridge, Bus, Ferry, Heliport, Marina, Mile, Intersection,
  Subway, Pier, Rail, Toll, Transit, Tunnel, WaterNav,
  Island, Lake, River,
  Center, Cemetery, Landmark, POI, Other
]);

var selectControl = new OpenLayers.Control.SelectFeature(
[
  Business,
  Hotel, Market, Restaurant,
  Library, Museum, Theater,
  PostSecondary, PrivateEarly, PrivateElementry, PrivateHigh, PrivateJunior, PrivateK8, PrivateK12,

],
{ onSelect: onFeatureSelect, onUnselect: onFeatureUnselect });

proprietaryMap.addControl(selectControl);
selectControl.activate();

如果您发布了最小化的代码版本，将对您有所帮助。首先阅读如何minimize your code的方法，然后可以使用jsfiddle.net主持一个小型演示。
