[CLOSED] Ext.NET Window Override

[softmachine2011]

Hi,

When I create a dynamic window with closeAction='destroy' or call to method destroy() of a window in ext.net v2.x it throws me a null reference exception in js side.

I saw that there is this function that makes an override of extjs base functionallity

// @source core/container/Container.js
Ext.Container.override({
...
onIFrameRelayedEvent: function (event) {
        var iframeEl = this.iframe, //Here for some reason iframe doesn't exists. this.iframe=undefined
            iframeXY = iframeEl.getXY(),
            eventXY = event.getXY();

        event.xy = [iframeXY[0] + eventXY[0], iframeXY[1] + eventXY[1]];

        event.injectEvent(iframeEl);

        event.xy = eventXY;
    }
...
});

This is how I open the windows:

var w = Ext.create("Ext.window.Window", {
                    closeAction: "destroy",
                    renderTo: Ext.getBody(),
                    title: 'window title',
                    itemID: 'sampleID',
                    itemDetailChanged: false,
                    modal: false,
                    resizable: true,
                    maximizable: false,
                    minimizable: false,
                    collapsible: false,
                    draggable: true,
                    isMinimized: false,
                    isMaximized: false,
                    minimizePosition: -1,
                    originalWidth: 500,
                    originalHeight: 500,
                    restoreTop: undefined,
                    restoreLeft: undefined,
                    minWidth: 500,
                    minHeight: 500,
                    width: 500,
                    height: 500,
                    isModal: false,
                    constrain: true,
                    items: [{
                        xtype: "netlabel",
                        text: "Sample"
                    }],
                    directEvents: {
                        hide: {
                            fn: function (el) {
                                debugger;
                            },
                            delay: 20
                        }
                    }
                });

                if (!Ext.isEmpty(w.parentTab))
                    w.parentTab.anyDetailOpened = true;

                w.on("beforehide", function () {
                    if (w.mandatoryClose == true)
                        return true;

                    var allowClose = true;

                    try {
                        if (!Ext.isEmpty(w.onClose))
                            allowClose = w.onClose(w, MyApp.Windows.applyClose);

                    } catch (ex) {
                        //No se puede ejecutar una funcion de una ventana ya cerrada 
                    }

                    return (allowClose);
                });

                if (w.isModal) {
                    w.tools["minimize"].hide();
                    w.tools["maximize"].hide();
                }

                w.show();

But in a sample project doesn't crash me.
How can I reproduce it for you to have a test example? When is iframe property deleted?

Hi,

We will try to reproduce.

Just a note.

Please don't define "directEvents" client side. It should be only generated with server DirectEvents.

Please use listeners + DirectMethods.

[Daniil]

Please update from SVN and re-test.

Hi,

With revision 4213 I got this error when I launch the application.



I reverted to 4211, and tested my case. With it seems to work right!

I would use rev. 4211 while this error is fixed.

Thanks!

I found that it is .NET bug
https://connect.microsoft.com/Visual...details/588847
http://connect.microsoft.com/VisualS...titydatasource

We will wrap that code by try/catch block. Do you use MVC apllication?

[softmachine2011]

Yes I use an MVC Application.

With rev 4214 works right again.

Thanks Vlad!
