My implementation of a TextCellEditor is the following, also adding a KeyListener:
fHoverTableViewerTextCellEditor = new TextCellEditor(fHoverTableViewer.getTable());
fHoverTableViewerTextCellEditor.getControl().addKeyListener(new KeyListener() {
private boolean isPressedKeyModifier = false;
private boolean isStateKeyModifier = false;
public void keyPressed(KeyEvent e) {
isPressedKeyModifier = e.keyCode > 0 && e.character == 0 && (e.keyCode & SWT.MODIFIER_MASK) != 0;
isStateKeyModifier = e.stateMask > 0 && (e.stateMask & SWT.MODIFIER_MASK) != 0;
String insertString = null;
String modifierString = Action.findModifierString(e.keyCode);
String modifierMask = Action.findModifierString(e.stateMask);
if (isPressedKeyModifier) {
insertString = Action.findModifierString(e.keyCode);
if (isStateKeyModifier) {
insertString= java.text.MessageFormat.format(Messages.HoverPreferencePage_insertModifierAndDelimiterAndModifier,
new Object[] { Action.findModifierString(e.keyCode), Action.findModifierString(e.stateMask) });
}
fHoverTableViewerTextCellEditor.setValue(insertString);
}
}
And then I bind:
fModifierTableViewerColumn.setEditingSupport(ObservableValueEditingSupport.create(fHoverTableViewer, context,
fHoverTableViewerTextCellEditor,
CellEditorProperties.control().value(WidgetProperties.text(SWT.Modify)),
HoverViewModel.getEditingDomain()));
But when I press enter I cannot see my content, or better, if I click again on the Cell, it shows my content, but it dies not show it after the "Editing" context is over.
What am I missing?

You need to call viewer.update(Object,null) after you modified the value.
