Problem with sub pages and how to get the right URL from whithin a parser

== Steps to reproduce ==

 1. Create a page with a subpage e.g.{{{
http://localhost:8080/OnePage/TwoPage}}}
 1. then attach from modern/img the files idea.png and tired.png to this page
 1. call the parser_problem from this page {{{
from MoinMoin.action import AttachFile

Dependencies = []
class Parser:
    def __init__(self, raw, request, **kw):
        self.raw = raw
        self.request = request
        self.form = request.form
        self._ = request.getText

    def format(self, formatter):
        current_pagename=formatter.page.page_name
        self.request.write(current_pagename)
	image='idea.png'
	example='tired.png'
	
	small={}
	small['src']=AttachFile.getAttachUrl(current_pagename,image,self.request)


        image_link=formatter.image(**small)
	
	webn_url="%(pagename)s?action=AttachFile&do=view&target=%(example)s" % {
	          "pagename":current_pagename,
		  "example":example}
	
	txt=(formatter.url(1,webn_url)+image_link+formatter.url(0))
	
	self.request.write(txt)

}}}


== Result ==

 * current_pagename looks good

 * I got if I look at the url in the status bar or if I copy it from the symbol
{{{
http://localhost:8080/OnePage/OnePage/TwoPage?action=AttachFile&do=view&target=tired.png
}}}

Where does the double ''!OnePage'' comes from?

All is ok if I use only !OnePage.

If I try {{{
http://localhost:8080/OnePage/TwoPage/ThreePage}}}

I got {{{
http://localhost:8080/OnePage/TwoPage/OnePage/TwoPage/ThreePage?action=AttachFile&do=view&target=tired.png
}}}

That's strange. May be I am blind and I have it in the code.

 Are you referring to image_link or webn_url here?
  ''image_link is right shown, if I send it to the browser webn_url is right {{{ OnePage/TwoPage?action=AttachFile&do=view&target=tired.png}}} but then if I build the URL by the formatter it goes wrong''
   Please use `action.AttachFile.getAttachUrl` in both cases.

    ''I got another solution. The hint with the absolute URL was perfect. It is easier by using wikiutil.link_tag.''
     {{{
text= 'text to show' 
url = 'where to jump'
link = wikiutil.link_tag(self.request, url, text=text,
                         formatter=formatter)
self.request.write(link)
}}}
