I am working on LiveCycle Designer ES4 on a dynamic form linked to a XSD database. I have setup a couple required fields via the Object panel option ("user entered - required").
When testing the form in the LiveCycle PDF Preview and/or Acrobat/Reader shows a fail in the required fields validation.
While the fields are empty I can tab from one required field to another and no alerts pop-up
Required fields still empty and I hit the submit button and again no alerts, plus the submission completes (via e-mail at this stage)
Am I missing a setting somewhere that is preventing the validation to run at submission?
That change did help trigger the native form validation on required fields. However it applied it to the wrong field! Go figure. In any I won't be able to work on 9.1 - the functions required by the form would need to be in version 10 or 11.
I just had a similar issue where required radio buttons were blocking the validation of the rest of the required fields. Under Form Properties > Defaults try setting the target version to 9.1 and see if that resolves your issue.
