  Hello all,
 I currently have a page in the xwiki/1.0 syntax :
 ----------
 #includeMacros("WikiCode.KBLMacros")
 <div style="text-align:center">
 #displayAllProjectsTable()
 </div>
 ----------
 When switching to xwiki/2.0 syntax, it generates this :
 ----------
 {{velocity filter="none"}}
 {{html clean="false" wiki="true"}}
 {{include document="WikiCode.KBLMacros"/}}
 <p/>
 (% style="text-align:center" %)(((
 #displayAllProjectsTable()
 )))
 {{/html}}
 {{/velocity}}
 ----------
 The problem is that in the page called WikiCode.KBLMacros,   i have a variable
called mainDocumentTitle and in the syntax
 2.0 generated, i can't read it from the macro displayAllProjectsTable.

 But if i move the line
 {{include document="WikiCode.KBLMacros"/}}
 before the line
 {{velocity filter="none"}}
 then it works again.
 Do all include have to be set outside the velocity code ? 
 Not exactly. In your case the problem is that you have:
 - velocity is executed inside {{velocity macro}}
 - then the result of velocity execution is parser with wiki
 syntax parser
 {{include}} is wiki syntax so when it's executed you already did
 interpreted the velocity code that is supposed to use the variable
 coming from WikiCode.KBLMacros. When you put it outside of
 {{velocity}} macro it's executed before the velocity macro itself you
 your use case is working.
 Sorry for that it's a converter bug but it's not very easy to handle
 in a generic way. Could you create a jira issue about {{include}} and
 {{velocity}} in converter to at least have it explained somewhere ?
