I have done it this way:
public class ValidationRowEditor extends TableViewRowEditor {
@Override
public void endEdit(boolean result) {
boolean valid = true;
if (result) {
Dictionary<String, Component> editors = getCellEditors();
Sequence<Column> cols = getTableView().getColumns();
for (int i = 0, n = cols.getLength(); i < n; i++) {
Component comp = editors.get(cols.get(i).getName());
if (comp instanceof TextInput) {
valid &= ((TextInput) comp).isTextValid();
}
}
}
if (!(result && !valid)) {
super.endEdit(result);
}
}
}
if one of the TextInput editors is not valid, user can only leave the editor by
pressing ESC.
It seems to work also with mouse, so it may also solve Lello's issues ( haven't
tested completely)

Sorry - I haven't looked at this code in a while. You should just be able to
override endEdit() and perform your validation. Don't call the base endEdit()
if validation fails.

Ok
but how can my app (my validators) tell the TableViewRowEditor that it should
not store the row?
it happens in TableViewRowEditor#endEdit(boolean result) which is invoked by
keyPressed().
So I should override keyPressed() and check the status of all validators before
invoking endEdit() ?

That's true, but it is up to your app to decide what constitutes "valid".

when a value is not valid you can still press return and then editing ends and
store() is also called.
So modifying the MouseListener will not be enough.
I believe that store() should not be invoked when there is a non valid value in
the row

The problem I am facing is that when you have any value which is not valid
you can still select a row of the table with the mouse and trigger a store()
method. This shouldn't be allowed whether or not strictValidation() is true
or false, since it returns an exception in any case. I should overwrite some
MouseListener in my custom TableRowEditor, but I can't find any.
Any suggestion?
