一些解决方案
------------------------

* IE下ModalPanel无法弹出的解决方案
    给ModalPanel添加属性
   
    .. code-block :: html
        
        onbeforeshow="removeTabHandlingFromPanel(jQuery('[id$=panelId]').get(0).component);"

    removeTabHandlingFormPanel()内部如下

    .. code-block :: javascript

        function removeTabHandlingFromPanel(modalPanelComponent){
             modalPanelComponent.lastOnfocus = function(event){};
             modalPanelComponent.firstOnfocus = function(event){};
             modalPanelComponent.processAllFocusElements = function(event){};
             modalPanelComponent.processTabindexes = function(event){};
             modalPanelComponent.restoreTabindexes = function(event){};
             modalPanelComponent.preventFocus = function(event){};
             modalPanelComponent.restoreFocus = function(event){};
        }
