Elements showing as required when they are not

[jo]

I have a form based on a shema in which there are a number of optional
elements. Although they are optional, infopath shows them as required
with an asterik. This seems to only occur on number types. String
elements are still optional.

I'm a little more than novice xml user but need some help. Why are the
elements showing as required and how can I prevent this?

Thanks,

Hello,

Did you add any validation for that field? Number field should accept
integer if you enter space or any string then it will show the validation.
