Fix Required Fields Error When Submitting a Spawned PDF Template
Question details
Users receive a required-fields-incomplete error when submitting a PDF form, caused by required fields located on a hidden template used to spawn new pages.

- Device & OS
- not provided
- Scenario
- A user attempts to submit an interactive PDF form that utilizes a hidden template to dynamically spawn new pages with required input fields.
- Observed behavior
- The form submission is blocked by an error stating that required fields are incomplete, even when all visible fields are filled, because the system is validating the empty fields on the hidden template.
Ensure you have access to a PDF editing software that supports form preparation and JavaScript, and create a backup of your original PDF form before modifying its field properties.
Modify Required Properties on Hidden Template Fields
Prevent the hidden template fields from blocking submission by disabling their required status prior to spawning, and reassigning it dynamically to the new field instances.
PDF form submission protocols validate all fields marked as required, including those existing on hidden templates. To bypass this issue, the fields on the hidden template must not be marked as required by default.
Open your PDF document in your PDF editor and enter the 'Form Editing' or 'Prepare Form' mode so that you can view and interact with all hidden fields.
Locate the specific form fields associated with the hidden template that is being used to spawn additional pages.
Right-click the target field, select Properties, and navigate to the General tab. Uncheck the 'Required' box and save your changes. Repeat this for all fields on the hidden template.
Configure your page-spawning JavaScript action to target the newly spawned field instances and change their required property to true (e.g., using getField("FieldName").required = true; after the spawn event).

Frequently Asked Questions
Why am I getting a required field missing error when all visible fields are filled in my PDF?
This usually occurs when your PDF contains hidden form fields or unspawned templates that are designated as 'Required'. The PDF software checks all required fields in the document hierarchy, including hidden ones, before allowing submission.
How do I make a spawned PDF field required dynamically using JavaScript?
You can use JavaScript within your PDF editor. Leave the original template field as not required. In the script that handles the page spawning, add code to target the newly generated field instance and change its required property to true.
Can I edit PDF form field properties in WPS Office?
Yes, WPS Office features a robust PDF editor that allows you to interact with forms, modify field properties, and adjust settings such as checking or unchecking the required or read-only status of a field.
