I prefer to say it with: with great power comes great responsibility.
I miss Anjo. I remember when committers who broke things were expected to fix them.

I got lucky and found the change that caused my problem: <https://github.com/wocommunity/wonder/commit/46baf84e143913e945de59364b5f7ec1f2b9c630#L30R119>
Adding back the (empty) takeValuesFromRequest method to my ERXSubmitButton subclass makes it work again. Is nobody else using ERXSubmitButton these days?

Hi all,
After updating Wonder from an integration-branch version dated 2012-11-25 to one dated 2013-06-08, an old application that uses ERXSubmitButton quite a bit, is throwing the exception quoted below. I have confirmed that this is due to the updated wonder frameworks, by going back to the previous set of wonder frameworks, while keeping the current version of the application and internal framework code. Removing the value binding doesn't help, as it will then default to "Save".
The same error message ("Cannot set value to 'Foo' in component 'bar' because value is not settable") was once posted to the list: <http://lists.apple.com/archives/webobjects-dev/2013/Feb/msg00103.html> Which makes me think that the commit that changed the behaviour occurred some time between 2012-11-25 and 2013-02-09. I've looked through the commits of ERXSubmitButton, ERXWOForm, ERXComponent, ERXSession, ERXAjaxApplication, ERXComponentRequestHandler and ERXApplication, but could not find anything "suspicious".
Before I start some lengthy debug session: Does someone have an idea what could be causing this?
