The following code should bind the "value" property of the text box to the string "Test".
Instead the binding expression "{{test}}" is left unparsed as the text box content. The binding expression within the sibling element is parsed correctly however.
<html>
<head>
<title></title>
<style type="text/css">
.sys-template { display:none; }
</style>
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjax.debug.js"></script>
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.debug.js"></script>
</head>
<body xmlns:sys="javascript:Sys"
xmlns:dataview="javascript:Sys.UI.DataView"
sys:activate="bindingTest">
<div id="bindingTest" class="sys-template"
sys:attach="dataview"
dataview:data="{{ { test : 'Test' } }}">
<input type="text" value="{{test}}" />
should contain: <span>{{test}}</span>
</div>
</body>
</html>
This same code works when linking to the corresponding scripts in the ASP.NET AJAX Preview 4 release (no longer available on CodePlex as far as I can tell, but contained in the sample ZIP on this post).
Is this a regression, or am I missing something?
