[jboss-user] [JBoss Seam] - JSF/Bean binding dropped when using s:link

Tue Jun 12 08:48:51 EDT 2007

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?
