With XWiki Syntax 2.0 we now have the ability to do: {{include document="groovypage"/}} where groovypage is a page using the {{groovy}} macro to define groovy code. If you want to forbid several executions of the {{groovy}} script you could use an if() inside it and check if a value is present in the session or application context (depending if you want it called once per user or per application).

Thanks Vincent, You're right it will be easier through context... Do "$context" (velocity) and "context" (groovy) variables refer to the application context or to the session context ?
