    JSF/Bean binding dropped when using s:link

    thatrichard Newbie

      Short version: When I navigate using an s:link then any data entered into form fields disappears. Everything works ok when I use commandLinks.

      Long version:
      I've created a tabbed form using a conversation. The user moves between tabs by clicking on links. At any time, the user can persist the form data by pressing a Save button.

      Here is the Session Bean and JSF pages (the first JSF page creates the tabs, the second creates a tab which is inserted into the first).

      Note that I've duplicated the tab links. The link with the 2 appended is implemented with commandLink and the second one with s:link.

      If I use the commandLinks, everthing behaves as expected. I can navigate between the tabs and enter data. When I hit save the data is persisted. However, when I use the s:links then the data disappears. For example, if I enter a last name and then navigate to the second tab and back, the last name has disappeared.

      Does anyone know what is going on?
