Hi,
I would like to export a rich:datatable to an Excel file like in the seam-excel example but i keep getting
"org.jboss.seam.excel.ExcelWorkbookException: A worksheet's value must be an Iterable, DataModel or Query"
Here's the service feeding the datatable
`@Stateful
@Scope(ScopeType.SESSION)
@Name("previsionHydroServiceBS")
public class PrevisionHydroServiceBO implements PrevisionHydroServiceBS {
@EJB
private PrevisionHydroDAS previsionHydroDAS;
@DataModel
private Map<String, String> previsions;
// blabla
@Factory("previsions")
public void populatePrevisionList() {
// ...
}`
my datatable
`<r:dataTable id="table_previsions" value="#{previsions}" var="prev" rows="48">
<r:column>
<f:facet name="header">
<h:outputText value="Tranche Horaire" />
</f:facet>
<h:outputText value="#{prev.key}" />
</r:column>
<r:column>
<f:facet name="header">
<h:outputText value="Prévision KW" />
</f:facet>
<h:outputText value="#{prev.value}" />
</r:column>
</r:dataTable>`
the command button
`<h:commandButton action="#{excelExporter.export('table_previsions')}" />`
My button is in a <form> scope but not my datatable, but that's not the cause of the problem i think.
The exception says that i need to feed the seam excel with a datamodel, but my map is tagged @datamodel, so that's not so helpful.
I am relatively new at web developpement, so the problem might be any dumb mistake, and i am sorry if it is.
If someone could help me, i'd be grateful.
Thanks
ps : sorry, it seems that the markups are not working
