Re: How to destroy/terminate xpages partial request?

Hi,

Dojo provides a method to cancel an xhr-Request. The only problem is that XSP won't give you direct access to the underlying xhr-Object; that is why you can not cancel the request via the XSP object directly. Here is a workaround which hijacks Dojo. You have to add this in a script block.

var xhrCall = null;

dojo.addOnLoad( function(){
    dojo._xhrPost = dojo.xhrPost;
    dojo._xhrGet = dojo.xhrGet;

    dojo.xhrPost = function( args ){
       xhrCall = dojo._xhrPost( args );
     }

    dojo.xhrGet = function( args ){
        xhrCall = dojo._xhrGet( args );
    }
});

Now, you are able to cancel a running partial refresh with a simple

xhrCall.cancel();

Normally, an error will be raised by the XSP if a refresh is canceled. To solve this you have to add a custom error handler to your refresh, f.e.

XSP.partialRefreshGet('id', { onError: function(){} } );

Hope this helps

I would like to use this code in the xsnippet for a responsive standby dialog. But I do not understand how to apply the " To solve this you have to add a custom error handler to your refresh, f.e." suggested solution. Can you provide some guidelines?
