Attempting two combine to IRenders into cumulative Renderer

Hi, I am trying to implement a quick custom renderer object to use with
the contrib Table component.
My goal is to combine a RenderString and an Image object into a single
IRender, so I can show a "..." after entries that are two long.
 
I realize I could manually write it out without the use of the
RenderString or Image components.. but I thought this would be more
elegant.
 
This is my code:
 
return new IRender()
                {
                    public void render( IMarkupWriter writer,
IRequestCycle cycle ) throws RequestCycleException
                    {
                        new RenderString( value.substring( 0,
value.length() - 4 ) ).render( writer, cycle );
                        net.sf.tapestry.html.Image image = new
net.sf.tapestry.html.Image();
                        image.setImage( cycle.getPage().getAsset(
"elipsis" ) );
                        image.render( writer, cycle );
                    }
                };
 
I am getting an exception on line 126 in ParameterManager.. so on this
line:
 
        IResourceResolver resolver =
_component.getPage().getEngine().getResourceResolver();
 
The stack trace is :
