ListGrid formatCellValue - loses standard formatting.

[jason.saunders]

If I override the formatCellValue function on a ListGrid, how do I call the standard formatting routines?

I seem to lose the ability to format images for instance - short of rewriting my own image formatter.

e.g.

    data = isc.DataSource.create({
        clientOnly: true,
        fields: [ 
            {name: "icon", type:"image"}, 
            {name:"description" }
        ],
        cacheData: [
            { icon: "[SKIN]/headerIcons/close.png", description: "Item 1" },
            { icon: "[SKIN]/headerIcons/close.png", description: "Item 2" }
        ]
    });

    isc.ListGrid.create({
        width: "100%",
        height: "100%",
        dataSource: data,
        autoFetchData: true
    });

Works fine. If I put a formatCellValue handler in;

    data = isc.DataSource.create({
        clientOnly: true,
        fields: [ 
            {name: "icon", type:"image"}, 
            {name:"description" }
        ],
        cacheData: [
            { icon: "[SKIN]/headerIcons/close.png", description: "Item 1" },
            { icon: "[SKIN]/headerIcons/close.png", description: "Item 2" }
        ]
    });

    isc.ListGrid.create({
        width: "100%",
        height: "100%",
        dataSource: data,
        autoFetchData: true,
        formatCellValue: function (value, record, rowNum, colNum) {
            return value;
        }
    });

Then my images no longer render. If I use;

return this.Super("formatCellValue", arguments);

then nothing renders.

Looking at ListGrid.js I can see that I seem to have to call the _typeFormatter of the field if it exists, but how do I call this internal function and is that the correct thing to do?

Anyone with any clues on this one? I don't want to have to workaround this if it turns out I've missed something obvious.

[jason.saunders]

OK, well I suppose the message is do not use formatCellValue.

[jason.saunders]

Have had to change it to use the deprecated getCellValue where the call;

this.Super("getCellValue", arguments);

does return the default formatted value, unlike;

this.Super("formatCellValue", arguments);

which does not.
