    Default 4.1beta2 IE8 runtime error?

    4.1beta2 IE8 runtime error?


    I used ExtJS4.1b2 with IE8 and encountered the runtime error.
    It's a problem of the framework


    ext-all-debug.js
    line 16116


    Microsoft JScript runtime error: 'null' is null or not an object


    Code:
    16107 if (Ext.isIEQuirks || Ext.isIE && Ext.ieVersion <= 8){
    16108     Ext.Array.forEach('Top Right Bottom Left'.split(' '), function(side){
    16109         var borderWidth = 'border' + side + 'Width',
    16110             borderStyle = 'border' + side + 'Style';
    16111 
    16112         Ext.dom.Element.prototype.styleHooks['border-' + side.toLowerCase() + '-width'] = {
    16113             name: borderWidth,
    16114             get: function (dom) {
    16115                 var currentStyle = dom.currentStyle;
    16116                 if (currentStyle[borderStyle] == 'none'){
    16117                     return '0px';
    16118                 }
    16119                 return currentStyle[borderWidth];
    16120             }
    16121         };
    16122     });
    16123 }

    sorry.
    Apparently, it seems to have been my problem.
    I was making the portlet using highcharts based on the portal application of the example.
    It occurred when Ext.Panel was used.
    However, it operated well when Ext.Container was used.

    My means is uncertain.

    Default same problem i met.

    same problem i met.


    by debugging it I see the dom.currentStyle value doesnt set to the variable, there for the next line variable currentStyle is null and thus throw out exception. the wierd thing is, I added a breakpoint and dom.currentStyle is null, but after the dom.currentStyle been watched, it generates a value. I've never seen this before, guess there is something hidden in the dom function.

    My solution is adding a patch:

    if(!currentStyle || currentStyle[borderStyle]=='none'){
    ...
    }

    not sure it is correct but at least the code runs smoothly now.

    I just checked beta-3 and it seems that the code in question no longer exists. You may wish to test against that version.
