[xwiki-users] evaluate programming rights?

Hello XWiki ers, on #xwiki, Sergiu was kind enough to indicate that my current bug, the fact that $!xwiki.getXWiki().Param(...) returns empty is a programming rights issue: the problem seems to be that the resource page, whose rendering is entirely made outside of the wiki-page-content. And I could verify that by having, in all pages where the above is empty, an output that of $doc.hasProgrammingRight() which is false. Question 1: how can I evaluate that another page has programming rights? Question 2: is there a way to give programming rights to everything in a space? to all code in included .vm files? thanks in advance Paul
