Hi Vincent,
I've solved the "save files" problem with absolute paths and it works,
however I've another problem, this time with the Velocity macro inside a
wiki page.
This is the exception that I've got:
*org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate
Velocity Macro for content [#if("$!request.evolver" == 1)
## Request for creating a new instance
##$services.evoS.parseBPXML('Home','BSS Rome')
$services.evoS.removeInstance('Take bike')
##$response.sendRedirect($xwiki.getURL('Main.WebHome'))
#else
#end
{{html}}
<form action="" id="newEvolution" method="POST">
<div>
<input type="hidden" name="evolver" value="1"/>
<span class="buttonwrapper">
<input type="submit" value="Evolve" class="button"/>
</span>
</div>
</form>
{{/html}}]
