Breaking: #70503 - EXT:form - Remove breakOnError option from wizard

See forge#70503


The validation option breakOnError is not supported anymore. The option has been removed completely.


The validation process cannot be interrupted anymore, i.e. the whole form will be validated and all error messages will be shown.

Affected Installations

Any installation that implements the breakOnError functionality.


The function has been removed without any substitution. Therefore there is no migration possible. The attribute can be manually removed from the form configuration. The wizard ignores the existence of breakOnError. Since TYPO3 7.5 it is possible to utilize HTML5 attributes to validate form elements on the fly. This could be used to emulate the behaviour.
