<h:head>
    <title>codeScanned</title>
</h:head>

<h:body>
    <h:form>
        <pe:codeScanner width="300" height="300">
            <p:ajax event="codeScanned" listener="#{codeScaner.onScanned}"/>

I use the same phone and browser, it works! but my code does't work.
I really don't know what the problem is? somebody can test my code? Who can help me debug my code?
Thanks!
