generateChangeLog does not work with enum

I used generateChangeLog to save a change log with an enum (MySQL) in it. Instead of the enum being placed as type="ENUM('field1','field2')", it wrote type="ENUM(2)" where 2 is the number of elements. I can fix it in the change log by myself but it will show up every time I will generate a changeLog.
