    [CLOSED] [1.3] Window.close() causing 'Microsoft JScript runtime error: 'Ext' is undefined' error when called from an IFRAME

    Hi, I'm creating a new window and trying to invoke the close method of that window from the resulting IFRAME using the close method on the parentAutoLoadControl object. When doing this I'm getting the 'Microsoft JScript runtime error: 'Ext' is undefined' error. When I call the hide method I do not have issues. I've also tried closing the window down from the parent and things are fine so I can only assume this is something to do with killing of the window from which the click originates.

    This appears to function correctly in Chrome, I haven't tested FF but isn't working in IE9. I'm also using Ext.net v1.3

    I've included code for both the Parent and Child below. Any help would be great.

    Thanks,

    Gav

    Hi,

    Please set up a small delay.
    <Click Handler="parentAutoLoadControl.close();" Delay="1" />
    I think it happens due to the difference in JavaScript browsers engines. IE often requires a small delay in such cases.

    Wow, how I've missed that for so long is beyond me but that fixes it. You can mark this ticket as closed.

    Thanks!
