What's the best way to refresh the data in a business object?  I know you can just call the fill method over again, but I have a situation where this is not going to work.  I am in edit mode on my form, but I have a few un-editable values on the form which may change.  If the values update I want it to reflect on the form.  If I call the fill method, it will take it out of edit mode and back to idle.  Is there a good way to do this?  I thought about having one business object linked to the values I want to be able to refresh, and one that just links off to the editable values that won't refresh. When I need to refresh and they are in edit mode, I only refresh the one business object.  When in idle, it would refresh both.  Is this the right way of thinking about it??
