[xwiki-users] Bulletin board app modification question

I've modified the bulletin board app by adding an edit link to BBCode.TopicClassSheet (between Quote and Delete) that links to $doc.getURL("edit", "editor=object&classname=BBCode.PostClass&object=$item.number"). This gives me the ability to edit a post by linking to the object editor for that post. But the object editor isn't very user friendly. I noticed towards the top of BBCode.TopicClassSheet, the context.action is checked to see if its "inline". This determines if a new thread is being created, and does what is necessary to create it. I'd like to change the edit link to point back to BBCode.TopicClassSheet but provide a different custom action. This way I could check for that action (say for instance "postEdit") and instead of providing the post as is, provide a form that lets me edit the object. My problem is, I don't know how to create a link to do this. I've tried some of my guesses, but it didn't work. Can someone tell me how to (within BBCode.TopicClassSheet) create a link to BBCode.TopicClassSheet but with a different custom action that would allow me to change the post from just a diplay to a form that allows the object to be edited? Hope that question makes sense. Thanks, Lenny
