Multiple popup window feature of related objects popup through id_to_windowname

[davidcooper]

In an app that has a cascading set of objects we required the ability to have multiple popup windows. In tabbed browsers this can work out well, especially when the tabs can cascade like the firefox tree-style view. To bring this support to django all that is required is an override for the two methods id_to_windowname and windowname_to_id at line 18 of django/contrib/admin/media/js/admin/RelatedObjectLookups.js, such as this:

var uniqueness=(new Date()).valueOf();

function id_to_windowname(text) {
    text = text.replace(/\./g, '__dot__');
    text = text.replace(/\-/g, '__dash__');
    return uniqueness + text;
}

function windowname_to_id(text) {
    text = text.replace(uniqueness, '');
    text = text.replace(/__dot__/g, '.');
    text = text.replace(/__dash__/g, '-');
    return text;
}

This trivial change to the 'name' of the window allows multiple caller-callee connections, even involving the same models, as used as the id.

This sounds interesting. Marking as DDN as it's unclear what the implications would be. Could you provide a more specific use case for this? Any proof that your suggested change wouldn't break any existing code would also be appreciated.

Sorry for ignoring this. I can say that I have used it on my site for sometime now without problem. I cannot imagine how any existing service would be impacted negatively, the change is pretty trivial and is isolated.
