    Default Ext.fly(...)' is null or not an object on IE7

    Hi,

    I have an extjs tree , on IE7 when tree is loaded if I try to click anywhere around the tree or expand a node I get the error Ext.fly(...)' is null or not an object and the page turns blank.
    After some research it was mentionned that I should override function getTarget with the below :
    Ext.override(Ext.EventObjectImpl, {
    getTarget : function(selector, maxDepth, returnEl){
    var targetElement;

    try {
    var target=(this.target||window.event.srcElement);
    targetElement = selector ? Ext.fly(target).findParent(selector, maxDepth, returnEl) : target;
    } catch(e) {
    targetElement = window.event.srcElement;
    }

    return targetElement;
    }

    });
    After overriding the function , the error is no longer throw but the page is still blank.
    The weird part is that when I resize the window the tree appears again but I still can't click anywhere without turning the page blank.

    If anyone can assist.

    Thank you.
