Ajax and multiple requests

[jeffzzang]

Let's say I have a page with an ajax-enabled component (a4j:commandLink) which executes code attached to its actionListener. Let's also assume that this method which it executes may take a long time to finish.

What happens if I click the a4j:commandLink and while the server is executing the method, I click the same commandLink again or I fire another ajax-enabled component. Does this screw up the JSF tree in any way? What are the implications and solutions? Thanks.

Current attributes set is not enought.
Let's look the following example. There is a data table, there is "remove item" link (h:commandLink) in each row. User clicks link in the first row twice quickly. As result the first and the second rows are removed.

I would like to disable more than one "remove item" event in queue, so the "ignoreDupRequests" attribute would be usefull. Currently I should manually disable "remove item" links until the first request is completed.

This looks like the problem in your application code. What is on the model level that allows to perform the action on the row that the link is not belong to?
What is on your page and what is in the java code.


And, no. RichFaces has no such customizable queue manager. No such plans for the closest future.

You could possibly disable the other links by using a4j:status onStart in combination with some javascript code (jquery comes to mind) and enable them again in onStop.
