Success! Looks like we've fixed this one. According to our records the fix was applied for TOUCH-1173 in a recent build.

    Default Destorying a button (itself) gives Uncaught TypeError: Cannot call method 'removeCls'

    Destorying a button (itself) gives Uncaught TypeError: Cannot call method 'removeCls'


    Hi,

    I have defined button (using ICONCLS) with-in a panel. As part of the handler (ontap), I preform some action and wanted to remove the button (that was tapped/pressed).

    I used panel.items.items[index for the button].destroy(), while the button is getting deleted/destroyed i get error

    52467 me.releasedTimeout = setTimeout(function() {
    52468 me.element.removeCls(me.getPressedCls());

    Basically me.element is null (as it has been removed)

    I tried used panel.remove(button item) the result is same.


    Is this a bug or there someother way of doing the same.

    This is giving me no issues:

    Code:
    var btn = Ext.create('Ext.Button', {
        text : 'hi'
    });
    
    var cnt = Ext.Viewport.add({
        items : btn
    });
    
    setTimeout(function() {
        btn.destroy();
    }, 1000);

    Hi,

    I tried deleting from javascript console and it works no issues. Issue is deleting the button when the button itself was pressed -- meaning on its own handler
    actionBar.add ({
    iconcls:'backButton'
    ,handler:function(b,e){
    <Some code>
    actionBar.remove(actionBar.items.items[0])
    }
    }

    Makes sense. It is because there is a timeout for the pressedCls, which is then going to try and remove it, from a button, which, no longer exists.

    Thanks,

    But this problem was not in Sencha 1.1 -- I see this error only in Sencha 2.0

    Yeah, I've added it as a bug to ST 2.0. As you know, ST is just in it's preview stage, so there are a few little issues like this..

    Are you sure you are on PR2? This seems to be already fixed.
