Dear Forum,
The Multi Page Form seems to have issues with Validation Errors.
When I define Multi Page Form pages which refer to the same Parent Form Field "page1_key", than I get Validation Errors.
When page1 has one or more validators "Mandatory" on, than on submit on the last page will raise Validation Error messages on the first page, even when everything has been correctly entered.
I'm not sure if the Parent Form Field references have something to do with this, but it happened to be configured this way in order to make entered fields on page1 available on the other pages page2, page3, etc.
Regards, Joost
