Are f_item_category and f_item_store reference fields? If so, they only get
the default "represent" validator if (a) you do not explicitly specify a
"requires" attribute and instead use the default validator, and (b) the
referenced table has a "format" attribute. Otherwise, you will need to
explicitly define the "represent" attributes.
