Splitting a renderkit-configuration in two or more files

Question

Hi
I develop a webapplication using JSF with additional components. Some of these components use VML which does only work in IE. To support Firefox we want to use a second renderkit which generates code for a SVG approach of our components.
The problem is that we splitted the components in several modules with an own faces-config.xml for each module. To keep it modular we want to define SVG-renderers for each module in these faces-config-files, too. The SVG-renderer should belong to the same renderkit, so we can easily switch to SVG-output if a user logs in from a Firefox browser.
Have a look at this little example:
/WEB-INF/moduleA/faces-config.xml:
<faces-config>
     <render-kit>
          <renderer>
               <component-family>map</component-family>
               <renderer-type>map</renderer-type>
               <renderer-class>com.example.component.renderkit.vml.MapRenderer</renderer-class>
          </renderer>
     </render-kit>
     <render-kit>
          <render-kit-id>SVG</render-kit-id>
          <render-kit-class>com.sun.faces.renderkit.RenderKitImpl</render-kit-class>
          <renderer>
               <component-family>map</component-family>
               <renderer-type>map</renderer-type>
               <renderer-class>com.example.component.renderkit.svg.MapRenderer</renderer-class>
          </renderer>
</faces-config>/WEB-INF/moduleB/faces-config.xml:
<faces-config>
     <render-kit>
          <renderer>
               <component-family>map</component-family>
               <renderer-type>tool</renderer-type>
               <renderer-class>com.example.component.renderkit.vml.ToolRenderer</renderer-class>
          </renderer>
     </render-kit>
     <render-kit>
          <render-kit-id>SVG</render-kit-id>
          <renderer>
               <component-family>map</component-family>
               <renderer-type>tool</renderer-type>
               <renderer-class>com.example.component.renderkit.svg.ToolRenderer</renderer-class>
          </renderer>
</faces-config>In this case JSF complains about a duplicated renderkit "SVG". If I rename one, both can`t be active at once. Can you tell me how to add further renderers to a renderkit in a separate faces-config?
Thank you for your help!

Most likely, you do everything right and will get what you want.
JSF does complains about a duplicated renderkit "SVG", but notifies you that definition from the two configuration files will be merged.
This merge is not a problem. It is a normal behavior described int he specification.
From the first sight, I do not see any conflicts in your files. As a result of merge you should have two renderes in the default render kit and two renderers in the SVG render kit.
