[OpenLayers-Users] display style.

[Erik Uzureau]

Murali,

Do you have some sample code that you could paste? It's hard to debug these
sort of things without a good stack trace.

One thing that comes to mind is are you setting the width and height
properties on your map div? the getCurrentSize() function below first tries
to read clientHeight/Width but if that fails, it uses the getDimensions()
function and then as last resort style.height and style.width.

--Erik

    /**
     * @private
     *
     * @returns A new OpenLayers.Size object with the dimensions of the map
div
     * @type OpenLayers.Size
     */
    getCurrentSize: function() {

        var size = new OpenLayers.Size(this.div.clientWidth,
                                       this.div.clientHeight);

        // Workaround for the fact that hidden elements return 0 for size.
        if (size.w == 0 && size.h == 0 || isNaN(size.w) && isNaN(size.h)) {
            var dim = OpenLayers.Element.getDimensions(this.div);
            size.w = dim.width;
            size.h = dim.height;
        }
        if (size.w == 0 && size.h == 0 || isNaN(size.w) && isNaN(size.h)) {
            size.w = parseInt(this.div.style.width);
            size.h = parseInt(this.div.style.height);
        }
        return size;
    },
