Jan Ziegler commented on RF-6947:
---------------------------------
Sorry I forgot to mention - yes I´m using tomahawk (tomahawk12-1.1.8). I also tried to remove the tomahawk filter from the web.xml but without success for rich:fileUpload.
As an additional information: I´m having no problems with an older 3.3.1 Snapshot e.g. 20090219.
Here´s the web.xml content:
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

<description> A very common problem in configuring
MyFaces-web-applications is that the Extensions-Filter is not
configured at all or improperly configured. This parameter will
check for a properly configured Extensions-Filter if it is needed by
the web-app. In most cases this check will work just fine, there
might be cases where an internal forward will bypass the
Extensions-Filter and the check will not work. If this is the case,
you can disable the check by setting this parameter to false.

<description> In some versions of MyFaces there is a context param
"org.apache.myfaces.PRETTY_HTML" that can be specified in the
web.xml to enable pretty output. However this option was never well
supported as it requires support from every renderer in order to
work. This feature may be removed from future versions of MyFaces.
</description>

<param-value>false</param-value>
</context-param>
<context-param>
<description> This parameter tells MyFaces if javascript code should be
allowed in the rendered HTML output. If javascript is allowed,
command_link anchors will have javascript code that submits the
corresponding form. If javascript is not allowed, the state saving
info and nested parameters will be added as url parameters. Default:
"true" </description>

<context-param>
<description> The view state can now be rendered with javascript. If
this feature is enabled (via context parameter
"org.apache.myfaces.VIEWSTATE_JAVASCRIPT") the view state hidden
inputs in the forms are rendered with empty value attributes. The
actual viewstate is then filled in on the client with a rendered
javascript function that simply iterates over all forms.

able to restore the former vertical scroll on every request.
Convenient feature if you have pages with long lists and you do not
want the browser page to always jump to the top if you trigger a
