That will happen when there's an implicit or explicit Converter associated with the type behind itemValue. An example of an implicit converter is @FacesConverter(forClass=String.class). It would run on any model value of type String.class. An explicit converter is one which you specify via converter attribute of the input component, but this isn't visible in your code snippet posted so far (unless you oversimplified the snippet without actually testing it).

At least, the generated value is recognizable as outcome of UUID.randomUUID().toString(), so if you search for that line of code in your code base, you will find the suspected converter. Perhaps it's kind of "generic entity converter" which you can find at several places on the Internet, but which you'd after all actually better not use.
