Hi Andrew, With regards to showing error messages “globally” for the form: you can just call Form.error(“message”) for that. If you then use a feedback panel with a ComponentFeedbackMessageFilter scoped to the form, it will work as expected.
For validating multiple fields at once, e.g. double entry of password, have a look at IFormValidator; You add it to the form and provide references to all components being validated. You can then choose yourself if you wish to report any errors on one of the components directly, or on the form.
