ListGrid refresh prevents user interaction

[gsaxena]

When a listgrid refreshes, the user cannot click on any part of the application until the listgrid has finished refreshing, i.e., the call acts as if it were a "blocking call". This seems odd, since we thought that as much as possible, GWT/javascript style is to avoid blocking. Is there a way to disable this "blocking" nature so the user can still click on other parts of the application while waiting for the listgrid to refresh?

See rpcRequest.showPrompt and also DataSource.showPrompt.

You can block or not block the UI as you like, but when you are not blocking you should think through all the interactions that the user might attempt while data is loading, and add code to prevent anything going wrong.
