In Internet Explorer 9 when an autocomplete popup is opened by clicking on the arrow button, it needs two clicks outside it to close it.
This can be reproduced with the following code:
<f:view>
<h:head></h:head>
<h:body>
<rich:autocomplete mode="client" minChars="0" autofill="false" showButton="true"
autocompleteList="#{fn:split('Test 1, Test 2, Test 3', ',')}" />
</h:body>
</f:view>
The problem is, that the handler for the blur event is not fired for the first click.
It seems to be a bug in RichFaces, so I filed a bug report. As I don’t think it will be fixed very soon and I can’t upgrade to a newer version, I am looking for a workaround.
It works when I add the following code to my page:
