Did anybody find a solution for this?

I am also facing this issue, that the confirmation message appears before validation.

I found a possible workaround but I still need some help to make it comletely working:

I could just disable the "Save" button until all fields have a value, however I don't want to create a separate rule for every control.

Is there an other easier way to say, that if any of the fields in the form is empty, a selected button should be disabled?

I believe that the confirmation message serves only for awareness: 'Are you sure you want to proceed?' - it can be useful in case the forms do not have any validation rules...

In my case however I had to convince users to get rid of this confirmation message due to another issue: when the validation is done through the JavaScript rather than the rules, the validation wasn't performed at all after closing this message box... By closing I mean clicking the red cross on the top-right corner of the message box, not by clicking Cancel button.

Another thing that users also liked was the custom message during the submission instead of blank page in the browser. It can take a while until users are redirected back to the list view when submission triggers the workflow.

@Jekaterina is there any documentation how this can be achieved. It looks really interesting.
