Description

The unit tests ought to cover this, but apparently don't. A TextField should convert empty strings to nulls if you call setConvertEmptyInputStringToNull(true) on it (which the constructors do by default).

However, this doesn't currently work:

• AbstractTextComponent#getConvertEmptyInputStringToNull() is only called from AbstractTextComponent#convertValue(String[]).
• AbstractTextComponent#convertValue(String[]) is called from FormComponent#convert(), but only if the component doesn't have a type assigned to it.
• As soon as you use a PropertyModel (which implements IObjectClassAwareModel), this means empty strings are no longer converted to nulls.

This is obviously a great big blocker and needs fixing ASAP.
