[xwiki-users] Image macro inside a recursive macro doesn't work for the first call

30 May 2008

      Hello,

I have a recursive velocity macro that calls the Image macro provided by
XWiki. Weirdly, the call doesn't work only for the first call of this
recursive function. All the subsequent ones (the really "recursive" calls)
render the image perfectly. For the first call what's rendered is the code
that calls the image macro, with the brackets and everything, as if I had
escaped it somehow.

Does anyway has any idea of what is happening?

Maybe it helps if you can see the code, so here it goes. The calls to my
macro and to the image macro are in bold:

#macro (createChildrenNodes $parentNodeName $childrenSkillList)
    #foreach ($skill in $childrenSkillList)

      #set ($iconStyleClass = "ygtv")
      #if($velocityCount == $childrenSkillList.size())
        #set($iconStyleClass = $iconStyleClass + "l")
      #else
        #set($iconStyleClass = $iconStyleClass + "t")
      #end
      #if ($skill.hasChildren)
         #set($iconStyleClass = $iconStyleClass + "p")
      #else
         #set($iconStyleClass = $iconStyleClass + "n")
      #end

      var node$skill.id = new YAHOO.widget.HTMLNode('<table border=0
cellpadding=0 cellspacing=0><tr><td><div
class="$iconStyleClass"></div></td><td><a href="./EditSkill?skillId=$
skill.id">$skill.name</a>  <a
href="./DefiningExistentSkills?do=delete&skillId=$skill.id">*{image:supprimer.bmp|13|alt=Click
to delete skill $skill.name}*</a></td></tr></table>', $parentNodeName,
true);
      *#createChildrenNodes("node$skill.id" $skill.children)*

    #end
  #end

  function treeInit()
  {
    var tree = new YAHOO.widget.TreeView("treeview");
    var root = tree.getRoot();
    *#createChildrenNodes('root' $xwiki.cartography.getSkillTree())*
    tree.draw();
  }
  treeInit();

Thanks,
