Redmine

Hi there,

I updated redmine from 2.3.0 to 3.3.0. Now I met a problem, below are repro steps.

1. Create a new issue
2. Update the issue to another status, which has required field in my workflow configuration. The required field is List format configured in Custom fields.
3. Choose a value in the list, save the issue successfully.
4. The filed value leaves empty after a success save.

Plus, I have some new findings. Let's call the custom field as Field-A, Field-A has three values a,b,c.

1. Set Field-A to a, save the issue.
2. The Field-A leaves empty.
3. Update the issue, set Field-A to b, save the issue.
4. The Field-A's value is successfully set to b
5. Update the issue, set Field-A to a (which is initially value in step 1), save the issue.
5. The Field-A's value is still b, but a is expected here.

If the initial value is b, the repeat steps 2-5, you will find the initial value can't be saved. But if you change the value of this field the save the issue, it works well.
