wow. Thank you! That's helped a lot!
.getValue() is the key to success if you use setDefaultFormProcessing = false!

Betreff: Re: why is the model empty?
Well, don't know what to tell you. It bypasses validation, which is
required in order to set the models to their values. If you submitted
akj123 in a text field that was an Integer, we could only set it after
validation (which in this case means the value could not be set on the
field). So, bypassing validation means that you must also bypass getting
your models updated. You can call textfield.getValue() (or similar - can't
remember exact name) to get the raw submitted value.

Did you look at the javadoc? [1]
It says:
Sets the defaultFormProcessing property. When false (default is true), all
validation and
form updating is bypassed and the onSubmit method of that button is called
directly, and the
onSubmit method of the parent form is not called. A common use for this is
to create a cancel
button.
So, yes, that would prevent the model from being updated.

That's not an immutable model. It's equivalent to new ModelString() -
which is fine for this use. Assuming the text field and the button are
within a form, and that he sets the value of the textfield programmatically
on the page, and submits the form, the model should be updated by the time
he gets to this onSubmit method.
