Subclassing Backgrid.Grid

[gxxcastillo]

I have something like:

var columns = [...];
var collection = new Backbone.Collection(...);

// This does not work
var CustomGrid = Backgrid.Grid.extend({
     columns: columns
    , className: 'backgrid customBackgrid'
});

var grid = new CustomGrid({collection: collection})

However, it fails to render and only seems to work if I call the Backgrid.Grid() constructor directly and pass it all the arguments:

// This works
var grid = new Backgrid.Grid({
     columns: columns
    , className: 'backgrid customBackgrid'
    , collection: collection
})

What am I doing wrong?

Changing the Grid.prototype.initialize routine seems to get things working. Would you like a pull request?

from:

options.columns = new Columns(options.columns);

to:

options.columns = new Columns(options.columns || this.columns);
