Hi Ashley,
I'm not sure I understand 100%. An example might help.
It sounds like you have something like a BrowseInvoices, which has a field "Total LineItems Value".
then you want o be able to click on the Value, go to the LineItems browse, edit the line items. Once that browse is closed then you want the Invoices browse to refresh to show the updated line-items value?
am I on the right track?
is the child browse going to be a popup? or a page?
why not just put the child on the page as a child of the invoices browse - like say the books example does? Then the things all take care of themselves...
cheers
Bruce
