Hi,
I am using GWT forms to do file uploads. In one of my cases i
want to validate the name given in the Textbox of the form. To
validate the name i have to request the server for the names available
already. To validate this inside the FormHandlers OnSubmit method i
request the server and on invalid name i cancel the form submit. But
before the response is received, the form handlers completes and
submits the form. How this can be resolved?
