Check if a numeric field has a value

[danieldotnet]

Hello,

I have a numeric field and I want another field to become a mandatory field
as soon as a number is in this numeric field. Unfortunately I did not find a
solution anywhere ...

Best regards,
Daniel

Hi Daniel,

You can use the expression `$number/string() castable as xs:decimal`,
assuming your number field is named `number`, which you put in the
Validations and Alerts tab, as shown below. And the GIF linked below also
shows what this lookalike at runtime.

You'll let me know if this works for you,
