[bug?] exception thrown in sendPage() skips the proper error handler

[Stefano Mazzocchi]

I'm still having fun with webdavapps and found something that looks 
suspiciously close to a bug in the way the flow and sitemap work 
together in case of an exception.

In the davmap, I added

    <map:handle-errors>
      <map:read src="error.html" mime-type="text/html" 
status-code="404"/>
    </map:handle-errors>

to handle all errors in the fastest and simplest possible way but if 
the error is triggered in a pipeline call from the flowscript, for 
example, in the davmap case

  function selectMethod() {
    var page = cocoon.parameters["page"];
    var method = cocoon.request.getMethod();
    cocoon.sendPage(method+"/"+page, null);
  }
then my error handler is skipped and the normal error page is presented.

I think this behavior is wrong: the flow is just a way to add scripting 
in the sitemap without hardcoding it in, but the call scope should be 
preserved, even for exceptions.

WDYT?
