let me explain with a simple example We have a flex screen with a data grid. The data in data grid is populated with java collection. The java collection contains stock data which comes from backend. In the backend every 0.5 second the stock data in collection is updated(we get market feed of data).
so every 0.5 second we need to refresh the flex data grid and update it with the backend data. So the question now is we need to make a asynch call every 0.5 sec to fetch the updated data. I am using blazeds to get the java collection but i dont think blazeds can be used to make asynchronous calls. That is where we want to use ajax to make the asynchronous call every 0.5 sec. thanks.
