If i understand what you mean, you want to repopulate the grid everytime the data are updated in the backend right ?
I think Blase DS does not support pushing Data to the client. Atleast not the free version. A solution could be to set up a timer that will poll data from the backend every 5s ? I think you can do that in as3 Dont get me wrong i dont want to keep you from using GWT, i just think that in your case there is a solution that is more effcient and esay to maintain then using GWT. But if you dont mind having some overhead plus a language explosion (MXML/AS3, JS, Java) and architecture problem in your project.
