I've run it, and there's bugs: 1) method 'getLayerByName' should be 'getLayersByName' 2) I've fixed #1 bug, but following exception was caught by Chrome: =================== Uncaught TypeError: Cannot read property 'test' of undefined OpenLayers.Map.OpenLayers.Class.getByMap.js:733 OpenLayers.Map.OpenLayers.Class.getLayersByMap.js:758 OpenLayers.Map.OpenLayers.Class.getLayersByNameMap.js:778 snap.OpenLayers.Control.Snapping.layerdmp.php:331 OpenLayers.Events.OpenLayers.Class.triggerEventEvents.js:765 OpenLayers.Layer.OpenLayers.Class.setVisibilityLayer.js:696 OpenLayers.Layer.Google.OpenLayers.Class.setVisibilityGoogle.js:171 OpenLayers.Map.OpenLayers.Class.setBaseLayerMap.js:1122 OpenLayers.Control.LayerSwitcher.OpenLayers.Class.onInputClickLayerSwitcher.js:377 (anonymous function) =================== I've tried to trace into OpenLayers code but haven't been found the solution. cheers, Herry -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Changing-Map-of-Overview-Map-Control-tp5904022p5908865.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
