[news.eclipse.dsdp.ercp] TextCellEditor does not work in TableViewer

[markus.bach@xxxxxxxxxxxxx (Markus Bach)]

Hi

I try to create a editable table wit eSWT 1.2 but without success. The 
CellModifier seems to work, because all of its methods get called in the 
proper order but the user does not have the chance to make any changes in 
the table, because no editor or even a cursor is shown. If I double click 
the field, tan modify gets called immediately.

Here is the code creating my table:

Table protocolTable = new Table(table, SWT.BORDER | SWT.H_SCROLL | 
SWT.V_SCROLL | SWT.FULL_SELECTION);
       TableViewer tableViewer = new TableViewer(protocolTable);

       tableViewer.getTable().setLayoutData(new 
GridData(GridData.FILL_BOTH));
       tableViewer.getTable().setLinesVisible(true);
       tableViewer.getTable().setHeaderVisible(true);

       tableViewer.setContentProvider(new 
ConfigurationProtocolTableContentProvider());
       tableViewer.setLabelProvider(new 
ConfigurationProtocolTableLabelProvider());
       tableViewer.setColumnProperties(new String[] { "DATE", 
"PROFILE_NAME", "INFO" });
       tableViewer.setCellModifier(new 
ConfigurationProtocolTableCellModifier(tableViewer));

       TableColumn columnDate = new TableColumn(tableViewer.getTable(), 
SWT.LEFT);
       columnDate.setText(Messages.getString("protocol_table_date"));
       columnDate.setWidth(110);

       TableColumn columnProfileName = new 
TableColumn(tableViewer.getTable(), SWT.LEFT);
       
columnProfileName.setText(Messages.getString("protocol_table_profilename"));
       columnProfileName.setWidth(200);

       TableColumn columnInfo = new TableColumn(tableViewer.getTable(), 
SWT.LEFT);
       columnInfo.setText(Messages.getString("protocol_table_info"));
       columnInfo.setWidth(400);

       tableViewer.setCellEditors(new CellEditor[] { null, null, new 
TextCellEditor(protocolTable) });

       tableViewer.setInput("1234567777");


And this is teh code of my CellModifier:

public class ConfigurationProtocolTableCellModifier implements 
ICellModifier {
   private TableViewer viewer = null;

   public ConfigurationProtocolTableCellModifier(TableViewer viewer) {
       this.viewer = viewer;
   }

   public final boolean canModify(final Object element, final String 
property) {
       return true;
   }

   public Object getValue(Object element, String property) {
       if (element instanceof DeviceProtocol) {
           DeviceProtocol protocol = (DeviceProtocol) element;
           return protocol.getProtocolInfo();
       }
       return "";
   }

   public void modify(Object element, String property, Object value) {
       if (element instanceof DeviceProtocol) {
           DeviceProtocol protocol = (DeviceProtocol) element;
           protocol.setProtocolInfo((String) value);

           viewer.refresh(protocol);
       }
   }
}

Does anybody know what I am doing wrong or is there a problem in the eSWT 
implementation?

Thanks

Markus
