Re: [xwiki-users] Scripting issue - xwiki

Hi again My problem was that in my Velocity script (page3) I forgot to add "$" in front of some variable names (Groovy doesn't use "$") so the real values were not passed across correctly and the object was not created correctly therefore NullPointerException (Null Pointer Exception). Anyway, for those who get stuck like me, this is the correct way to include groovy class within another groovy class. Velocity script : #set($wsd = $xwiki.parseGroovyFromPage("GroovyScripts.Class1")) #set($discard2 = $wsd.setXWiki($xwiki, $context)); Groovy Class1: def groovyHTTP = xwiki.parseGroovyFromPage("GroovyScripts.Class2"); //then groovyHTTP.someMethod(someParam); Groovy Class2: //some methods ********************* Some tags: Include groovy class in velocity script, pass value from velocity to groovy ********************* Ajdin -----Original Message----- From: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] On Behalf Of Ajdin Brandic Sent: 12 January 2009 13:50 To: XWiki Users Subject: [xwiki-users] Scripting issue - xwiki Hi I wander if anyone can help. I have found a discussion on IRC between users "asyd" and "lucaa" but the was no answer to the problem. I have two Groovy Classes saved as two pages page1 and page2. I also have some scripting outside class in page1. So page1 class requires an instance of page2 class and I use xwiki.parseGroovyFromPage("somespace.page2") which works fine until I introduce a third page / script called page3. In page3 I use xwiki.parseGroovyFromPage("somespace.page1") "REMEMBER: page1 also uses parseGroovyFromPage to call page2". I get NullPinterException when page1 class tries to access a method of page2 class. I then tried to create an instance of page1 and page 2 classes in my page3 script then pass page2 instance as parameter to page1 but still the same error. Is there any way around this except putting all content (page1 and page2) into one class? I would really appreciate some feedback. If you require the code to be sent I'll gladly do that.
