    Default How to cancel a drop after an Ajax failure

    How to cancel a drop after an Ajax failure


    Hello everybody,

    I cannot cancel a drop event after an Ajax failure, e.g.

    function dropHandler(dropEvent) {
    ...
    dropEvent.cancel = false;
    Ext.Ajax.request {
    ...
    failure: {
    dropEvent.cancel = true;
    alert("On failure: "+dropEvent.cancel);
    }
    }
    alert("After request: "+dropEvent.cancel);
    }

    First the "After request: false" message is printed, then the "On failure: true" but it is late. How can I affectively cancel the drop on ajax failure? Any tips?

    Thanks in advance
    George

    George,


    What UI widget are you using?

    I guess I am using asynchronous widgets. I use nodeType: 'async' in my trees, if this is what you are asking. I understand the fact that ajax request is asynchronous, but how can you handle such cases when you want to cancel a drop after an synchronous ajax request?

    You can't! The drop happened aeons (In processor time) before the Ajax request creeps back along the wire!

    I would say, return false from onNotifyDrop, cache the drop event, if the ajax event is successful, complete the drop. I've done this before and it works.
