Making a form field mandatory

Posted on by Community Member

I have set the Mandatory property for a form field to Yes and the field is underlined in red accordingly to indicate that it must be filled in but on record creation I am able to Close/Esc and the record will save without prompting for the mandatory fields:

What have I missed?

    This has been an issue for a long time.  It's more common in dialog forms where the field is set mandatory in code.  Ultimately, if your field must contain data, you should check for that in validateWrite() to be certain.

    Thanks, and correct me if I am wrong, but is validateWrite called on record creation when no fields are changed?

    The validateWrite() method is called just prior to saving a record from the UX.  If it returns false, the write is aborted.  You can use validateField() and validateFieldValue() also to validate individual fields, but those are only called in response to a field actually changing in the UX, so in your scenario they might not be called at all.

    Since validateWrite() is only called by the UX, a more drastic approach is to check in the write() method itself, and throw an error there on invalid data, since that method does not return a value.  You can also validate data in the .update() and .insert() methods, which would work even outside of the UX, which means it could catch attempts to insert/update invalid data even from X++ code.

    I will work on those useful suggestions.

    It is annoying that just setting the Mandatory property does not work consistently. It works elsewhere.
