optionGroup -> callback does not fire

I think you need to add #beOnChange or something similar. That will add the script for the callback.

Hi Sabine,

You mean you want the callback to fire when the selection has changed?
You need to intercept the change event and trigger the callback serialization:

html select
        onChange: (html jQuery ajax serializeThis);
        callback: ...

Johan

This is a common mistake, I believe we even have a Slime rule for this.
