| | | - JSF/Bean binding dropped when using s:link | - JSF/Bean binding dropped when using s:link 2007-06-12 - By thatrichard
Back
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?
