I generally load cargo data with one or a few XHR requests right after the application loads, but for really dynamic DDLs or SuggestBoxes, you don't have a choice. If you're doing something simple like the first DDL has 10 options and the second DDL has 10 options that change depending on the first DDL's value, you just load all 110 values into the browser and write the logic to deal with changing the lists (enabling/disabling controls, changing focus, etc) in GWT.

Thanks Steve for ur response. i tought about this but this wont help me with my project because most of the fields present in the form are dynamic ones so sending a XHR request for field would be very expensive. could u please suggest any another way around.

The compiled HTML and JavaScript runs in the browser, so you need to make a GWT-RPC or XMLHTTPRequest call to the server for the list contents.Hang in there ... once you get over the hump it makes a lot more sense! Try using the GWT plugin and Eclipse ... when you generate a new project there is a greeting service that shows how the client-server communication is done.Good luck!smoyer--On Wed, Sep 29, 2010 at 3:16 AM, Rahul <jainrahul273@gmail.com> wrote:
