Retrieving a variable of an older version doesnt work anymore. This feature was still working in 2.1.103.

<wiki:HistoryIterator id="currentPage">

  <wiki:Variable var='versionLabel' default=" "/> 

</wiki:HistoryIterator>

See also VersionLabel --DF

Here's a workaround which seems to solve the problem. Apparently the wiki metadata of a page only gets initialised by a call to textToHTML. Obviously, this is not done as you iterate over different versions of a page. Below you find the additional java in the jsp which does the trick. -- DF

          <wiki:HistoryIterator id="currentPage">
                <%
                   //need to run textToHtml so that variables get initialised again !!
                   //Ugh!
                   WikiContext cc = (WikiContext) c.clone();
                   cc.setPage(currentPage);
                   String pagedata = cc.getEngine().getPureText( currentPage );
                   cc.getEngine().textToHTML( cc, pagedata );                   
                %>
                <wiki:Variable var='versionLabel' default=" "/> 
            </wiki:HistoryIterator>
