    Default [Serious] Settings itemHeight to 0 in list causing Tab to hang and leak memory

    [Serious] Settings itemHeight to 0 in list causing Tab to hang and leak memory


    For Sencha 2.1.

    Settings itemHeight to 0 in list causing Browser / Tab to hang and memory of the that Browser/ Tab growing steady and fast.

    Simple example:

    Code:
    /*global Ext:false */
    Ext.application({
        launch:function () {
            Ext.create('Ext.List', {
                fullscreen:true,
                itemTpl:'{title}',
                            itemHeight:0,
                data:[
                    { title:'Item 1' },
                    { title:'Item 2' },
                    { title:'Item 3' },
                    { title:'Item 4' }
                ]
            });
        } // launch
    }); // application()
    After executing this piece of code you will get unresponsive Browser or Tab.
    Tested on Chrome under Windows 7. Memory will keep growing fast as long as hanging process running.

    Expected behavior: Tab should not hang, List should contain all items with height 0.

    I'm not quite sure why you would do that but indeed it should technically work.

    Thanks for the report! I have opened a bug in our bug tracker.

    No problem. I agree, settings it to 0 doesn't make much sense and we've found this accidentally but impact is severe so I thought it needed attention.
