I may be missing the obvious, but how do you programmatically update the data on a separate module on the same page? For example, in one module, I click on a button that adds an item to a table. In a separate module on the same page, I would like to show the newly added item. Therefore, what is the best way to refresh the contents of just a single module on a page? I guess this would be a similar type of situation as when one module is a shopping cart and the other module is a list of items that each have a button to allow that item to be added to the shopping cart. Then what is the best way to show the live, up-to-date contents of the shopping cart without refreshing the entire page?Thanks.
