Re: [platform-ui-dev] UI Guidelines v2.1 Feedback

While this workaround may work, Gaby's and Martin's points are valid. The
wizard framework could give you better support here.
Gaby, please open a bug report against Platform UI with the details here.
Thanks,

Next/Finish are not enabled based on message state, but test
isPageComplete(). To make your wizard behave according to the
guidelines, call setPageComplete(getErrorMessage() == null &&
getMessage() == null) at the end of field validation.
