[xwiki-devs] Save document before adding new object

I was happy enough with simple solution, which required saving document before adding new object: #set($redirect=$xwiki.getRequestURL()) {{html}}<a href="$tdoc.getURL("objectadd","classname=Space.ObjectClass&xredirect= ${redirect}")&form_token=$!services.csrf.getToken()">Add object</a>{{/html}} Though for "average users" it could be hard to digest. Therefore I'm analysing Object edit mode form, where it works. I checked that link generation in #macro(displayAddObject $class) of the editobject.vm doesn't do the magic and I suppose it is somewhere in JavaScript. Can you provide some hints how it is actually done? Thanks in advance! Valdis
