> # Login as admin to console
> #  Define a connector and a resource (say resource-ldap on embedded mode). 
> # Create a USER mapping and map, for example, a Date attribute (say loginDate) with a
string value on the resource (say street on ldap, does not matter the meaning)
> # Define a JEXL transformer for that mapping row like this 
> {code:java}
> value.toString().contains("T") ? value.toString().split("T")[0].replaceAll("-", "") :
value  {code}
> Or a Java/Groovy transformer with this beforePropagation:
> {code:java}
>     public List<PlainAttrValue> beforePropagation(
>             final Item item, 
>             final Entity entity, 
>             final List<PlainAttrValue> values) {
>         
>         if (values != null && !values.isEmpty()) {
>             values.forEach(value -> {
>                 Date originalValue = value.getDateValue();
>                 if (originalValue != null) {
>                     value.setBinaryValue(null);
>                     value.setBooleanValue(null);
>                     value.setDateValue(null);
>                     value.setDoubleValue(null);
>                     value.setLongValue(null);
>                     value.setStringValue(makeSomeChanges(values.get(0).getDateValue()));
>                 }
>             });
>         }
>         return values;
>     }
> {code}
> You will notice that the value propagated is not the one changed by the transformer,
sometimes (like this case) you'll get an NPE:
