Hi, i am adding Users to a group as shown below d want to prevent that a user be added to a group twice. It is not working this way.

if( null == groupDoc.getXObject(groupDocumentReference, "member", xwikiname)){

I never used this method, and its javadoc could be improved, are you sure it does what you think ? ;) You could use something like (to be checked): xwiki.getUser("username", context).isUserInGroup("group")

// Add a member object to document BaseObject memberObj = groupDoc.newXObject( groupClass.getDocumentReference(), context); memberObj.setStringValue("member", xwikiname);

context.getWiki().saveDocument(groupDoc, context); }else log.error("the user already existed in the requested group...");

You say it doesn't work, but do you see that log ? What happens ?

I will appreciate any help. Thanks _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users

So you're saying that getXObject returns null even if there is a matching object? Can you try it outside the context of your current code? Thanks, Marius On Tue, Jun 10, 2014 at 10:06 PM, Daniel Ebanja <[email protected]> wrote:
