    [CLOSED] [1.0] Javascript error when generating id for an element after SVN update

    Got latest from SVN at 1:17pm. Now I am getting a weird javascript error in one of my pages. I can not reproduce in a simple example. The page is fairly complex and uses a grid with lockinggridview. The javascript error is the generic 'Object doesn't contain this property or method' at

    Ext class
        id : function(el, prefix){
            el = Ext.getDom(el, true) || {};
            if (!el.id) {
                el.id = (prefix || "ext-gen") + (++idSeed); // error when trying to set id of an element.  
            }
            return el.id;
        },

    The element el is of type DispHTMLDOMTextNode .

    RE: [CLOSED] [1.0] Javascript error when generating id for an element after SVN update

    I can reproduce this using lockinggridview. Bug in Lockgridview's initElement function. Here's sample code:

    <script runat="server">
    protected void Page_Load(object sender, EventArgs e) {
        if (!X.IsAjaxRequest) {
            this.GridPanel1.Store.Primary.DataSource = new object[]
            {
