 Unfortunately, there is no "matchingCityAndZipCode" field in your form, 
 so all that Symfony can do for you is display the error on top of the form.

+Here are the rules to understand the left and the right side of the mapping:
 
  * The left side contains property paths. 
- * If the violation is generated on a property or method of a class, its path is simply propertyName. 
- * If the violation is generated on an entry of an array or ArrayAccess object, the property path is [indexName]. 
- * You can construct nested property paths by concatenating them, separating properties by dots, 
-   * for example: addresses[work].matchingCityAndZipCode
- *The right side contains simply the names of fields in the form.
- * The left side of the error mapping also accepts a dot ., which refers to the field itself. 
- That means that any error added to the field is added to the given nested field instead.
