[OpenLayers-Users] strange behavior with wrong click event coordinates and drag pan

[Puneet Kishor]

I am experiencing a strange behavior that perhaps someone can help me troubleshoot. I am trying to make some custom mods to OpenLayers 2.11 -- nothing fancy, nothing in the JavaScript, only some of the buttons and images. So, I made a copy of my OL installation, and called it OpenLayers-copy, and replaced my OL script line in my web page like so

    - <script type="text/javascript" src="path/to/lib/OpenLayers-2.11/OpenLayers.js"></script>
    + <script type="text/javascript" src="path/to/lib/OpenLayers-copy/OpenLayers.js"></script>

    var map = new OpenLayers.Map("map", {
        "controls": [
          - new OpenLayers.Control.LayerSwitcher(),
          - new OpenLayers.Control.Navigation(),
          - new OpenLayers.Control.PanZoom(),
          + new OpenLayers.Control.LayerSwitcher({
          +     "roundedCornerColor": "rgba(0,0,0,0.8)"
          + }),
          + new OpenLayers.Control.ZoomPanel(),    
            new OpenLayers.Control.MousePosition({
                  "div": document.getElementById("coords"), 
                  "numDigits": 2
            })
        ],
        "projection": new OpenLayers.Projection("EPSG:900913"),
        "displayProjection": new OpenLayers.Projection("EPSG:4326"),
        "units": "m",
        "maxResolution": 156543.0339,
        "maxExtent": new OpenLayers.Bounds(-20037508, -20037508, 20037508, 20037508)
    });
    
    map.events.register("click", map, collections);
    
    "collections": function(e) {
        var lonlat = map.getLonLatFromViewPortPx(e.xy).transform(
            new OpenLayers.Projection("EPSG:900913"),
            new OpenLayers.Projection("EPSG:4326")
        );
        
        .. do something with lng/lat ..
    }


That is the extent of my OL changes. I am now seeing the following two behaviors that are foxing me --

1. The mouse display shows the correct mouse position in lng lat, however, the actual point clicked on (for further querying is off by several tens of degrees. For example, if I click at [-78.71, 43.33], the actual point calculated by the click event listener is [-61.45, 61.61]. Why?

2. I am unable to drag and pan the map. On the other hand, if I bring back Control.Navigation and Control.PanZoom then I am able to drag pan the map. I want to be able to drag pan the map, but I don't want to show the PanZoom controls. How can I achieve that?

Many thanks,
