[xwiki-devs] Rendering Groovy Script in Objects

I am investigation the possibility to write Panels in Groovy. Unfortunately I am not able to figure out: - if I XWiki would render Groovy script code by itself and if how ? - If not can I render a Groovy script form another Groovy script ? BTW I was stuck for a while when trying to create my own BlogPostTemplate because XWiki would not allow me to run it as Groovy script even if I gave myself programming rights. But when I wrote the BlogPostSheet as Groovy class and loaded it inside the Velocity script of the BlogPostTemplate it worked perfectly. Now I am wondering why I could not execute the Groovy script if I can circumvent this restriction so easily. Cheers - Andy
