Strange behavior of ComboBoxs

[lithian]

It's only a question about a strange behavior of ComboBoxs that I don't understand. In the doQuery method of ComboBox the filter is done by modify the baseParams attribute of the relative store. Why not simly pass the filter to the load method of the store.

The question seems trivial but if you use the store after the call of doQuery you post an unexpected parameter to the server.

Thanks,
Lithian.
