    Default Ext JS 4.1.2 (GA) Now Available - Support Only

    Today we are very pleased to announce that Ext JS 4.1.2 GA is available for support customers. The download can be found in the support portal.

    In addition to the handful of bugs we have fixed (see below), there are a few minor features that were added as part of this maintenance release:
    • New XTemplate "foreach" directive to iterate object properties.
    • Binary Ajax - just add "binary:true" to the request call to get a byte array in responseBytes.
    • DomQuery now supports namespaces.
    • Likewise, XML Reader supports namespace prefixes

    The "foreach" directive works like this:

    PHP Code:
        <tpl foreach="obj">
    The "$" and "." replacements are populated by the property name and value, respectively.

    Another new feature is destroyable listeners.

    Observable.addListeners (or "on") returns a Destroyable object. This is an object which implements the destroy() method which removes the listeners that the call added.

    To illustrate what Animal is saying...

    PHP Code:
        this.cleanups cmp.on({
    change: function () {
    // ... yes even this :)
    destroyabletrue // create destroyable object
    Then removing those listeners:

    PHP Code:

    // or

    Ext.destroy(this.cleanups);  // works if cleanups was not setup yet 
    This is similar to managed listeners but is more granular. It is most helpful for re-bindable relationships between objects.

    Good stuff; hope it works for me this time! Couldn't get our application working in 4.1.1...

    Are Evan's tree speedups in there, i.e. significant NodeInterface.removeAll fix?

    @Don, Good work, I can see a lot of fixes in this release. Can you confirm what's happening with the framework performance issues? Specifically in IE 7/8 but effecting the all browsers in general terms.

    Hmm, just tried 4.1.2 and get exactly the same issue I had in 4.1.1.

    Hard to determine exactly what is going on at present, so I'll settle for describing the effect...

    - Start with empty state, so cleared local storage or cookie, whatever you use.
    - Open a non-modal stateful window, such that the position and size will be written to state storage.
    - Close the window, and open again.
    The window does not appear unless you resize the viewport (then appears at 0,0), or you clear your state - it has contrainHeader turned on, so that may be a factor in why it appears on resize.

    Turning off the statefulness(!) of the window solves the problem.
    Modal windows appear to be fine too.

    Any thoughts?

    There's an example of pretty much exactly what you describe at /examples/state.

    The window position/size is persisted to a cookie. You can close it and then hit the button again and everything is restored as you'd expect.

    Yeah, I assumed it is something that should work, and that you will have tested.

    It seems that the pos in applyState is [-10000, -10000].

    When the window launches (the 2nd, problematic time) I see:
    Which seems correct, then around 200ms later:
    getState, that returns: {"width":650,"height":450,"maximized":false,"size":{"width":650,"height":450},"pos":[-10000,-10000]}
    Will keep digging...

    Edit: Hmm, hideMode on a window now defaults to offset, which sets position to -10000, -10000...
    Sure we're closing the windows, but will check.
