Wicket tables with empty data list

I am using Wicket DataTable to display a table. If the data list, which contains the data to be displayed inside the table, is empty then the table gets rendered with all the column headers and a label in the first row saying "No Records Found".

Is there any way to remove this label if the data list is empty and show only the column headers?

The output is produced by the NoRecordsToolbar. It seems like you don't use a plain DataTable but a DefaultDataTable instead which adds the NoRecordsToolbar in its constructor.

You have (at least) three options:

  • Create a new subclass of DataTable which doesn't add the NoRecordsToolbar.
  • Set the resource key datatable.no-records-found to an empty value.
  • Use the DefaultDataTable but remove the NoRecordsToolbar. Use dataTable.getBottomToolbars().visitChildren(NoRecordsToolbar.class) and remove it. That's not my favorite option because it seems a bit too brittle.
