Hi Mark,
We have successfully integrated multiple attachment upload feature but the application is throwing message "Object has been changed by another user...................." when Save button is clicked. In our example we are using 2 objects. Parent object has 1 child object as 1 to many relationship in grid format. Once all the documents are selected and attached in one go, then the user clicks on Save button in Parent object form, this informational/error message appears.
Why does the user have to refresh the parent object when it should be handled by default. If we auto refresh the parent object form, then the user is navigated back to top of the form, which is again increasing user activity and thus annoying the user.
Test bsv is below. Password is AwareIM.
