Thanks

>>How would that work with a Browser Front End? I have been assuming that calls should go from the from the front end to the BO not vice versa. If the BO starts calling methods in the Front End then it seems to me you have a problem because what if someone uses Excel as the front end etc. The BO has no control over what front end is used so I have been avoiding any calls from the BO to the front end.
