How Do I Avoid Automatically Setting Fields to Uppercase?

Model attributes that are also key fields are automatically coerced to be in uppercase. You can block this behavior on a field-by-field basis by defining the notUppercaseFields() function in your TabMenu's user exit file to return an array of field names that should not be converted.

Example:

function notUppercaseFields() {
   return ['ELEM_ATT$AT_NAME']
}

You can also provide a "global" override for an entire TabMenu by setting the shouldNotAutoUppercase variable to true:

var shouldNotAutoUppercase = true;
