----------------------------------------------------------------
I'm sorry, I missed one important piece that needs to be in place for this to
fail. A response header filter that forces IE Edge mode like this:
{code}
<filter>
<filter-name>X-UA-Compatible Filter</filter-name>
<filter-class>com.mycompany.ResponseHeaderFilter</filter-class>
<init-param>
<param-name>headerName</param-name>
<param-value>X-UA-Compatible</param-value>
</init-param>
<init-param>
<param-name>headerValue</param-name>
<param-value>IE=edge</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>X-UA-Compatible Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
{code}
I'm attaching a new quickstart with that filter in place.
I have absolutely no idea how upgrading Wicket could cause this to break. We
have this logic in place for years and it works until Wicket 6.8.0.
Could you please try once again with the new quickstart?
