IE Event is null

[Prescot]

Hi all

I am trying to simulate event in IE. 

                input.set.value("newValue");

                input.trigger("blur");

HTML code:

<input type="text" id="email" name="email" onblur="test()">

and the function "test"

function test(){

alert("1");

alert(event.srcElement);

}

when I try it manually in IE ,I get it work perfectly, but when I run using Webspec  it pop's up the first alert but then says: "Unable to get value of the property 'srcElement': object is null or undefined".

Why when I run Webspec it simalates the event but then it says that the event is null?

Thanks
