RE: TableView Objects with nested Objects

[Separovic, Jason]

Hi Roger,

Thanks for the response. I was just missing the setSelectedItemKey bit as per 
the tutorial.
So my nested object is now binding correctly thanks.

ListButton listButton = new ListButton();
ArrayList listData = new ArrayList();

listData.add(null);
       for(Object o : dao.getAll(f.getType())) {
              listData.add(o);
       }

       String key = f.getName();
       listButton.setListData(listData);
       listButton.setSelectedItemKey(key);
       tableViewRowEditor.getCellEditors().put(key, listButton);

I'm just trying to figure out how to use a different representation of the 
object instead of the default toString() method. Is the ItemRenderer 
responsible for what is displayed in the button?
Do I create my own renderer if I what to use the getName() object method 
instead of the toString() method?

Cheers,

Jason

Hi Jason,
                In a short word, yes, the row editors rely on data binding.  
For instance, the TableViewRowEditor.beginEdit method has this code:
        // Get the data being edited
        List<?> tableData = tableViewArgument.getTableData();
        Object tableRow = tableData.get(rowIndexArgument);

        // Load the row data into the editor components
        tablePane.load(tableRow);

                And likewise the endEdit method does this:
            // Update the row data
            List<Object> tableData = (List<Object>)tableView.getTableData();
            Object tableRow = tableData.get(rowIndex);
            tablePane.store(tableRow);

                The standard Pivot Data Binding tutorial is quite helpful:  
http://pivot.apache.org/tutorials/data-binding.html
                Basically your data can be a POJO using bean methods to get and 
set the data, and your column names must match the bean property names.

                If you need more help, just ask - we've been through this 
before.

Thanks,
