Redmine

I don't know if this is already fixed, I'm looking for and no result has been found.

We have a custom field at beginning isn't require, passed few time, we changed this behaviour. some issues hadn't got defined a value for this custom field.
If we try to update the issue, we puts some hours in the field spent_time, but don't put any value in the custom field required then submit.

We have a error, but the time_entry don't have rollback

I'm using redmine 1.0.2 (stable)
I've patched the Issue::save_issue_with_child_records adding a "raise" if "params"
isn't valid
