Question

I’m getting an error when parsing checkboxes in a table that is loaded with AJAX, but I get an error saying the widget with that id is already registered:
“Error(‘Tried to register widget with id==userListUncheckAll but that id is already registered’)”

And I’m guessing this happens because we take out the current table, then replace it with what ever we get back from the AJAX call, and thus the element id’s would be the same. Is there a way to “unregister” the widgets or something similar?

I found the answer for this myself, so I’ll put it here for others:

If you have a set of id’s that you know will need to be “unregistered”, create an array of the id names:

try {
    dojo.parser.parse();
} catch (e) {
    var ids = ['id1', 'id2', 'id3'];
    dijit.registry.forEach(function(widget) {
        //remove this check if you want to unregister all widgets
        if (dojo.indexOf(ids, id) { 
            widget.destroyRecursive();
        }
    });
    dojo.parser.parse();
}

Works like a charm.
