  Hello,
 I try to create a page in XWiki/2.0 generating some JSON data but I
 have
 some problems and I have to go back to XWiki/1.0...
 * when you write this in a page MySpace.MyPage:
 [
  { "field" : "value" }
 ]
 you call MySpace.MyPage?xpage=plain and you get some HTML code:
<p><br/>.{ "field" : "value"...<br/></p>
 this is not good for the JSON parser...
 * So I try using the verbatim {{{}}}
 {{{
 [
  { "field" : "value" }
 ]
 }}}
 and I call again MySpace.MyPage?xpage=plain and I get:
 <pre>
 [
  { "field" : "value" }
 ]
 </pre>
 Ok for the JSON data but the <pre></pre> is not good also for JSON
 parser...
 * If I write some velocity inside:
 {{velocity}}
 #doit()
 [
  { "field" : "${value}" }
 ]
 {{/velocity}
 I get some <!-- velocity-macros --> comments or something like that
 before
 my json encoded into HTML...
 not good for the JSON parser also...
 What's the solution in XWiki/2.0 to make a page generate JSON?
 For the time being, I use XWiki/1.0 but this is not a viable solution.
 thanks
 Pascal
