New subject: [xwiki-users] groovy.lang.MissingMethodException - No signatureof method

29 Jan 2009

***** I'm posting this again cos the whole post got mixed up with
another post "Custom class field as field on a different class
<http://n2.nabble.com/Custom-class-field-as-field-on-a-different-class-t
p2152709p2239310.html> " *****

As written previously I'm trying to trigger some code on document save.

Sergiu Dumitriu explained issue I had with
(com.xpn.xwiki.doc.XWikiDocument vs.
com.xpn.xwiki.api.Document).  I got most the stuff to work except (last
two lines of code) I am not able to save image from url as attachment.

I get Wrapped Exception: No signature of method
com.xpn.xwiki.doc.XWikiDocument.addAttachment() is applicable for
argument types: (java.lang.String, [B, com.xpn.xwiki.XWikiContext)
values: {"notif1.png", [-119,.., ["vcontext":...]}

Looking at the documentation at
http://maven.xwiki.org/site/xwiki-core-parent/xwiki-core/apidocs/com/xpn
/xwiki/doc/XWikiDocument.html
Says " XWikiAttachment | addAttachment(java.lang.String fileName, byte[]
data, XWikiContext context) "

Have I got type issue here or???

This is what I'm doing
def doc = xwiki.getDocument(docName, context); //use this for
com.xpn.xwiki.XWiki def tmpElList = el.split("[\"]") def umlImage =
tmpElList[1] def imgAsBites =
xwiki.getURLContentAsBytes("http://www.websequencediagrams.com/index.p…
"+umlImage, context);
def newAttachment = doc.addAttachment(filenameToSavaAs,imgAsBites,
context); //use this for com.xpn.xwiki.XWiki
saveAttachmentContent(newAttachment,context);

Has anyone had a similar problem?

  Hi

 I'm trying to execute another script on "Save" event.  I've created a 
 notification class (based on xwiki example
 http://dev.xwiki.org/xwiki/bin/view/Drafts/GroovyNotifications) and 
 pointed to it in "Administration > Programming > Notification pages".

 This script gets called every time which is fine and when I try to 
 display name of a document that is being saved (doc.fullName) all 
 works well. document name it works fine but when I try to display one 
 of the fieldnames doc.display('Summary') I get

 groovy.lang.MissingMethodException: No signature of method
 com.xpn.xwiki.doc.XWikiDocument.display() is applicable for argument
 types: (java.lang.String) values: {"Summary"}

 I tried 
   def tmpDoc = context.getWiki().getDocument(doc.fullName, context); 
 But again fullName is OK but display('Summary') isn't

 Am I missing something in my syntax?  How do I make document values 
 available in my Notification class?  
As you see, that is not an api object, but an internal class
(com.xpn.xwiki.doc.XWikiDocument vs. com.xpn.xwiki.api.Document). This
means that API methods don't work, unless they have an equivalent in the
other class.

You can either look at the methods of the XWikiDocument class, or get an
API object and work with it (new com.xpn.xwiki.apiDocument(tmpDoc)
