App crashes when adding a SettingsFlyout event handler

Question

That's the HTML file for my SettingsFlyout:

<!DOCTYPE HTML>
<html>
<head>
    <title>User settings</title>
    <link rel="stylesheet" href="/css/default.css" />
    <script src="/js/user_settings.js"></script>
</head>
<body>

    <script>

        function beforeShowHandler(event) {
        }
    </script>

    <!-- BEGINTEMPLATE: Template code for an empty Settings Flyout. -->
    <!-- Each settings flyout should be defined in its own HTML file. -->
    <!-- Set the width to 'narrow' for a narrow settings flyout. -->
    <!-- Set the background color for the header to the background color defined for your
             app tile in the manifest. -->
    <div id="userSettingsDiv" data-win-control="WinJS.UI.SettingsFlyout" aria-label="App defaults settings flyout"
        data-win-options="{width:'wide',onbeforeshow:beforeShowHandler}">
        <div class="win-header" style="background-color: #dbf9ff">
            <button type="button" onclick="WinJS.UI.SettingsFlyout.show()" class="win-backbutton"></button>

            <div class="win-label">User account</div>
        </div>
        <div class="win-content">
            Your API user key:
            <input type="text" readonly="readonly" id="txtApiUserKey" />
            <br />
            <button id="btnRequestUserKey">Request new one</button>

            <div id="divRequestUserKey">
                <hr />
                Username:
                <input type="text" size="20" id="txtUsername" />
                Password:
                <input type="password" size="20" id="txtPassword" />

            </div>

        </div>
    </div>
    <!-- ENDTEMPLATE -->

    
</body>
</html>

If I remove the event handler, the app won't crash anymore:

<div id="userSettingsDiv" data-win-control="WinJS.UI.SettingsFlyout" aria-label="App defaults settings flyout"
        data-win-options="{width:'wide'}">

Hi PCF,

Got it... The key was looking at the Output window when the exception was thrown.

Add this to your code:

onBeforeShow.supportedForProcessing = true;

Do not use inline script for Metro style apps. Put your handler in your JS file. Be aware of scoping issues as well, if it is in an anonymous function you should expose it using WinJS.Namespace.Define...

Thanks for your answer. But my app still crashes with this JS (included via <script>):

(function () {
    "use strict";


    function onBeforeShow(event) {
        console.log("Hello World!");
    }

    WinJS.Namespace.define("UserSettingsUI", { beforeShowHandler: onBeforeShow });

})();

// My DIV

<div id="userSettingsDiv" data-win-control="WinJS.UI.SettingsFlyout" aria-label="App defaults settings flyout"
        data-win-options="{width:'wide',onbeforeshow:UserSettingsUI.beforeShowHandler}">

PS: The ApplicationSettings example also uses inline scripts so I thought this is the way to go.

Thanks PCF,

Thanks for the repro code. I will give this a go locally and see what is going on.

You should always separate your code from the HTML. If you do not you cannot take advantage of ByteCode cacheing:

@jpsanders - I ran into a similar issue today, so my question is "why" do I need to say that my function / event handler is supported for processing?

The sample app that I downloaded "App Settings Sample" does not set supportedForProcessing = true on the handlers defined in that sample, so I am curious what is likely different about my application, thus requiring me to set this option to true?

The code that I want to execute in the onbeforeshow event handler is located in my own JS module... so my data-win-options of my SettingsFlyout look similar to this:

data-win-options="{width:'wide', onbeforeshow:BDS.Plugins.TemplatePlugin.loadSettings(), onbeforehide:BDS.Plugins.TemplatePlugin.saveSettings()}"

Hi Dog,

Most of the samples don't declare strict processing: http://msdn.microsoft.com/en-us/library/windows/apps/Hh987021.aspx (which is why you would need to add this).

The templates and your code should!
