    Default [2.3.0] Checkbox/Radio label in IE8 strict mode

    [2.3.0] Checkbox/Radio label in IE8 strict mode


    We recently added a doctype to our pages to encourage IE8 to use standards mode, and noticed it affected positioning of the checkbox labels, especially in a CheckboxGroup (see attachment: checkboxgroup-strict.jpg). Taking off the doctype fixed the issue (see attachment: checkboxgroup-quirks.jpg). It appears to have something to do with the resizeEl.

    Here is the test case:
    HTML Code:
    <!DOCTYPE HTML>
    <html>
        <head>
            <link rel="stylesheet" type="text/css" href="/ExtJS/2.3.0/resources/css/ext-all.css"></link>
            <script type="text/javascript" src="/ExtJS/2.3.0/adapter/ext/ext-base.js"></script>
            <script type="text/javascript" src="/ExtJS/2.3.0/ext-all-debug.js"></script>
            <script type="text/javascript">
                Ext.BLANK_IMAGE_URL = "/ExtJS/2.3.0/resources/images/default/s.gif";
                Ext.onReady( function() {
                    var w = new Ext.Window({
                        title: "Test Combo",
                        layout: "anchor",
                        bodyStyle: "padding: 5px;",
                        resizable: true,
                        width: 450,
                        height: 200,
                        items: [{
                            xtype: "checkboxgroup",
                            hideLabel: true,
                            name: "description_tables",
                            anchor: "0",
                            columns: 5,
                            defaults: {getResizeEl: function(){ return this.wrap; } },
                            items: [{
                                boxLabel: "Requests",
                                inputValue: "request"
                            }, {
                                boxLabel: "Journals",
                                inputValue: "journal"
                            }, {
                                boxLabel: "Solutions",
                                inputValue: "solution"
                            }, {
                                boxLabel: "Calls",
                                inputValue: "call"
                            }, {
                                boxLabel: "Assignments",
                                inputValue: "assignment"
                            }]
                        }]
                    });
                    w.show();
                });
            </script>
        </head>
        <body></body>
    </html>
    I tried it with 3.0 and didn't see any problem, so I used the 3.0 getResizeEl() method in an override with the 2.3.0 libraries, and that fixed the problem:

    Code:
    Ext.override(Ext.form.Checkbox, {
        getResizeEl: function() {
        	return this.wrap;
        }
    });
    I guess since it's fixed in 3.0, this is more of a FYI to the community.
