Support for key value binding is still very limited in GNUstep. Most
likely we are just missing a call to our internal method
reverseSetValueFor: here. We are calling this method from [NSControl
sendAction:to:] and this only gets called when you leave the text fields
with the return key. In that case the values seem to get properly
stored. What seems to be missing is a similar call when the field is
changed by any other way.
Does anybody know, when we should send the action for a text field?
Perhaps we have to send that regardless of the way the field gets changed?
