Cannot save "Personal information registration" form if no "Sampling date" or "RNA Later date" is entered

[Nicklas Nordborg]

This ticket replaces #320.

There is a problem saving the "Personal information registration" form when the "Sampling date" and "RNA Later date" fields are emtpy. If there are no date+time values, the "Create" button doesn't work.

There is a workaround... Use 'Tab' (or the mouse) to step through the input fields so that each date+time box is selected and deselected at least once. The "Create" button will now work.

I think the problem is that when the form is loaded all fields starts out in 'invalid' state. Each field is usually validated when it loses the input focus. Empty date+time are considered valid by the validation function, but this is only called when:

1. There are date+time values when the form is loaded
2. The date+time fields are deselected

The solution is that the "Sampling date" and "RNA Later date" should start in 'valid' state when the form is loaded.
