keyup Event works no at Production version

Hi Anton,

Can you explain a little what you are doing? Which browser are you using?
If you just have a simple alert in an input on keyup this works for me.

<input type="text" value="">
        <s:event b:on="keyup">
                <s:task b:action="alert" b:value="keyup event triggered" />
        </s:event>
</input>
