Ext.direct buffer

I have a question about Ext.direct.addProvider. I am using a remoter provider. I know there is an option to add buffer for multiple requests. But what i am looking for is a buffer that waits for XXX amount of time, and only then sends the request. Also, is there a way to send the request when a user clicks on a butt开发者_如何学JAVAon ?

Thx, Yoni

okay, i found an attribute enableBuffer which you can specify an XXX amount of time to send the request.

for the second question, is there a way to send the request when a user clicks on a button ?
