Partial update doesn't work with primefaces 4.0 and IE9 in compatibility view

Question

Simple login page doesn't show growl message in IE9 in compatibility view.

The code is:

<p:commandButton id="login_button" value="Login" 
   actionListener="#{logonBean.login}" update="@form"/>

The ajax request is broken and looks like:

javax.faces.partial.ajax=true&javax.faces.source=login_Form%3Alogin_button&javax.faces.partial.execute=%40all&javax.faces.partial.render=undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined&login_Form

If I specify partialSubmit="false" nothing is changed.

For Primefaces showcase everything works perfect.

In normal mode all is ok as well as for Chrome and FireFox browsers.

Answer 1

By default IE9 in compatibility view works as IE7.

And IE7 is no more supported by Primefaces (since version 3.5) .

Compatibility version can be changed via Developer Tools -> Browser Mode to IE8 as the minimal version of browser supported by Primefaces.

I couldn't figure out how to change it by default to IE8 (most likely by fixing registry). Also native IE8 works a little bit different from the one in compatibility view (for instance, the attribute target="_blank" in native mode opens a new window, but in compatibility view it opens a new tab).

So for testing purposes the way is to install a Virtual PC with Windows XP Mode and test application for compatibility issues with the native IE8 browser.
