    Default Unanswered: IE9, Unable to get value of the property 'viewIndex': object is null or undefined

    Unanswered: IE9, Unable to get value of the property 'viewIndex': object is null or undefined


    Hi folks! we're refactoring an application that uses these paths in order to use Ext, don't know the exactly version but it seems to be a beta or RC version.
    Code:
        
         <script type="text/javascript" src="/app_name/js/ext-4.1-pr1/ext.js"></script>
        <script type="text/javascript" src="/app_name/js/ext-4.1-pr1/ext-all.js"></script>
    The problem is when using TreePanel expandAll method and selecting a node using getSelectionModel().select(node).

    Sometimes it works great and some others it crashes when using IE9, not happening the same in IE8 or IE7.

    It's throwing the next error message in IE9:
    << Unable to get value of the property 'viewIndex': object is null or undefined >>
    and it's in ext-all.js.

    These is the callstack that IE9 shows:
    > indexOf
    onExpand
    fire
    continueFireEvent
    fireEvent
    onNodeExpand
    fire
    continueFireEvent
    fireEvent
    Anonymous Function
    callback
    onBeforeNodeExpand
    fire
    continueFireEvent
    fireEvent
    Anonymous Function
    fire
    continueFireEvent
    fireEvent
    expand
    expandChildren
    expand
    expandAll

    Thanks in advance.

    This is before or after you are changing the path to the new version?

    Hi,
    We're not changing path to a newer version, the point is I'd like to know if the problem it's throwing is because of problems with IE9.

    Treepanel is already with data loaded, but sometimes when calling expandAll it throws error with viewIndex inside ext files.

    thanks
