UiBinder works with ToggleButton

Question

I like the new GWT2 UiBinder, however it is unclear whether some things are achievable using the declarative user interface style.

For example, ToggleButton accepts only instances of an image during construction (there are no settings for up / down images). As far as I understand, UiBinder works in a JavaBean-like reflective way, where the assigned attributes are mapped to the corresponding setters. Is this style possible with widgets like ToggleButton, where certain attributes must be specified at build time?

<g:ToggleButton ui:field="myBtn"></g:ToggleButton>
