I'm fairly new to AJAX and starting to discover some of the issues that need to be dealt with. Recently I've discovered the problem of clicking on a button twice before the first click's response is received. For example.. I have a list of items with a "REMOVE" button. If I click on the remove button, it might take a few seconds for the screen to update and the item to be removed. During this time the button on the screen does not represent the state on the server, and clicking again might cause an error condition since I might be trying to remove a non-existant item.
I guess in general, my question is. Should an AJAX framework allow the execution of further AJAX requests in parallel? Is there in any provision in Tacos or Dojo or other frameworks that would disallow input until the response for the previous request is received? Is this something that belongs in the AJAX framework or should this be handled in the application? I remember first seeing this issue in non-ajax frameworks with submitting a form multiple times. In this case the framework used javascript to allow only one click on the submit button. Any thoughts? ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
