>Basing the parameterized view to a key in the parent isn't a good idea for reasons you're running into now. Instead, base it on a variable, and when you need to requery the view, change the value of the variable to match the key of the parent. Also, this way you can open the view without the parent by just initializing the variable.

Hi, Barbara, thanks very much. I also found, (in Effective Techniques, I think) that the tables are initialized in the order in which they were added to the data environment.
