My question is about the memory that groovy uses. If I write groovy code and put it in a web page. Then two people open that web page at the same time, does the groovy code interact from both instances? What I am trying to determine is if I put the following code on a page, if there will be issues? def observation = Utils.getComponent(ObservationManager.class) observation.removeListener("Renamer") def listener = new DocumentRenamer(xwiki, xcontext) observation.addListener(listener) The line that removes the listener uses a string. That string matches what is returned by the getName() of the listener class to identify it. My concern is that if person A opens the web page, it will create a listener called "Renamer". Then person B opens the page, the above code would remove person A listener before adding its listener. Another way to say it is, Is there one ObservationManager for all pages on the server or does each page have its own ObservationManager? -- View this message in context: http://xwiki.475771.n2.nabble.com/Groovy-Is-memory-space-shared-between-pag… Sent from the XWiki- Dev mailing list archive at Nabble.com. _______________________________________________ devs mailing list devs(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/devs
