[xwiki-devs] [Gsoc - 2009] XWIKI-3337 Jira Issue

Hi, I am interested in solving this Jira issue and I have been working on it. Its about displaying a warning to user when creating a user with a user name that already exists. Issue occurs when adding users from admin account. Below are the given steps to generate it Administration -> 'Users' -> Add New User -> Try creating user with same user name -> Nothing happens (or warning) Adding a user from register button displays warning and uses warnings defined in registerinline.vm called from register.vm template. I have started looking at the xwiki-core code, specifically com.xpn.xwiki.web. What I found is as follows when adding a user with same user name, when creating a new user from RegisterAction class -> xwiki.createUser(true,"edit",context) returns -3 indicating user already exists. And when adding from Administration panel I found it calls a template 'registeruser?ajax=1.vm' that is not in /templates folder. There fore, can you suggest me some steps to display a warning to user, when adding users from Administration panel. It uses Ajax to display 'add new user' UI. Here I am not clear on what template is being called and what to look for the next step. I have just stuck with this. I thought of sending a mail, I would get some points to continue with.
