[xwiki-users] Dynamically create objects on inline-edit page

I am trying to add a dynamic number of objects (all of the same type) to a document from the inline-edit page. The workflow that I would like is for the user to click an "Add Requirement" button and a row is populated on the page below the edit-list of existing requirements that is blank and can be added to. The user can do this multiple times, then click the "Save & View" button and it is all saved. I have figured out how to create objects during the initial rendering of the edit page, but not how to do it dynamically. Any suggestions would be greatly appreciated. Thanks! --Matthew
