Problems with form re-populating functions

[eluser]Trae R.[/eluser]
I have discovered that unless a form field has a validation rule associated with it that the Form Helper set_ functions will not re-populate the value at all when the form is loaded again.

As a workaround I typically create a rule for every field, even if it's something as simple as trim. I believe xss_filter is another validation rule that should be applied to almost any user entry fields anyway, so getting in that habit would be one solution to the "issue".

Does anyone out there know a way around not having to set a validation rule for every field you want to set_?
