Howto set Parent Value with drop down list (resolved)

Hi, I was looking for a way to set Parent Value with drop down list when user edit a page... I found this solution: I modify the forms "Panels: DocumentInformation" (/xwiki/bin/inline/Panels/DocumentInformation) like this: I replace lines: **************** <input type="text" id="xwikidocparentinput2" name="parent" value="$!tdoc.parent" size="30"/> **************** by **************** <select name="parent" class="panelselect"> <option value="$!tdoc.parent" selected="selected">$!tdoc.parent</option> <option value="">-Empty \*-</option> #foreach($subdoc in $xwiki.getSpaceDocsName("$doc.web")) <option value="$subdoc">$subdoc</option> #end </select> **************** The forms contain: **************** #set($pages = $tdoc.includedPages) #largepanelheader("XWiki document information") <dl><dt><label for="xwikidocparentinput2">$msg.get("parentfield"):</label></dt> <dd> <select name="parent" class="panelselect"> <option value="$!tdoc.parent" selected="selected">$!tdoc.parent</option> <option value="">-Vide \*-</option> #foreach($subdoc in $xwiki.getSpaceDocsName("$doc.web")) <option value="$subdoc">$subdoc</option> #end </select></dd> #if($pages.size() != 0) #if($pages.size() == 1) <dt>$xwiki.parseMessage("editincludepagemsgone"):</dt> #else <dt>$xwiki.parseMessage("editincludepagemsgmore"):</dt> #end <dd> <table summary="$msg.get("includeddocumentssummary")" id="xwikiincludeddocuments"> <tbody> #foreach ($page in $pages) <tr><td><a href="$xwiki.getURL($page, "view")">$page</a></td> <td class="xwikibuttonlink"><a href="$xwiki.getURL($page, "edit")">$msg.get("edit")</a></td></tr> #end </tbody> </table></dd> #end </dl> #template("tagedit.vm") #panelfooter()
