Netbeans Visual Web Selecting Rows

The UI presentation layer doesn’t hold state about which rows were selected.

Winston Prakash outlines how selecting a single row in Netbeans JSF table can be done, but it was a little roundabout.

Here’s a simpler take on it:

Bind a TableRowGroup’s selected attribute to a property on your page.

       <ui:tableRowGroup
             binding="#{Page1.tableRowGroup2}"
             id="tableRowGroup2"
            selected="#{Page1.selected}" 
            sourceData="#{Page1.myDataProvider}"
            sourceVar="currentRow">

Next just write the callback function, in our case, the selected row is the current cursor row, but it could be anything of course:

public boolean getSelected()
{
    RowKey rk = (RowKey) getValue("#{currentRow.tableRow}");
    return rk.equals(myDataProvider.getCursorRow());
}
