<s:autoUpdateDataTable [ all standard dataTable attributes allowed ]
[ preserveDataModel="{true|false}" ]
[ forceIdIndexFormula="value-binding" ]
[ sortColumn="value-binding" ]
[ sortAscending="value-binding" ]
[ preserveSort="{true|false}" ]
[ frequency="value-binding" ]>
standard dataTable body (<h:column> tags and optional "header" and "footer" facets)
</t:command_sortheader>
<s:autoUpdateDataTable>
Instructions
frequency - defines the time in seconds between the Ajax-Requests
Note - This component is different to others, it uses Ajax mechanisms to fetch data from the server, thus the backend binding can and will be used outside of the standard JSF lifecycle to deliver the data.
Use the autoUpdateDataTable tag always within a form tag.
It is also not very advisable, to put some input fields (or checkboxes, radio buttons, etc.) into the dataTable, since after every submit (which happens periodically) all the form data is cleared.
see examples/ajaxDataTableSingle.jsp for an example.
