GWT 2.1 and the editor engine, how?

Question

I am very confused by the new mecanism editor with GWT 2.1.

I cannot figure out how to provide errors with a simple TextBox.

For example, I want a TextBox where the text size is more than 6 (for password).

How can I just provide a delegate to this text field to handle this check and use this text field in the mecanism editor?

In addition, I do not understand the differences between editors and editor subtypes. How to use these two functions to create your own editor widget?

official documentation is here: http://code.google.com/intl/fr-FR/webtoolkit/doc/latest/DevGuideUiEditors.html But this is not very clear.
