What's the point of using a org.jdesktop.beansbinding.Validator ?

Using the beans binding, I can specify a org.jdesktop.beansbinding.Validator.
Fine, I created one and specified it.
It lets me specify an error code and error message.
It looks like it SHOULD be called automatically by the bean.
Now, what's the point?
I can enter an invalid value into my text field that has the validator, and get no indication whatsoever that it is an invalid value.

I haven't found any settings anywhere that look like they would affect this.

Now that I have the org.jdesktop.beansbinding source code I can see what the problem is.

While NetBeans will do all the bindings and assign the validators, it doesn't seem to create a BindingListener to actually DO something when a Validator fails.
There doesn't seem to be any way of doing this via the GUI editor, it looks like I'll have to create my own BindingListener and add it to the BindingGroup after the call to initComponents().

Or you can file an issue against it, telling the workaround too.

Ok, I did. Hopefully I didn't screw up too badly on the report...

Well, if the developer needs more information he will ask you in time.
