--------------------------------------

[~geoffcallender], is this still an issue? Can you give an example that doesn't require additional dependencies?

>                 Key: TAP5-2255
>                 URL: https://issues.apache.org/jira/browse/TAP5-2255
>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: tapestry-beanvalidator, tapestry-core
>    Affects Versions: 5.4
>            Reporter: Geoff Callender
>
> I have an entity field that the getter and setter convert between types (field is Date, getter and setter convert from/to JodaTime's DateMidnight). 
> Form detects @NotNull on the field, but BeanEditForm doesn't. BeanEditForm detects @NotNull on the getter, but Form doesn't. So I have to provide @NotNull on the field AND the getter. Shouldn't Form and BeanEditForm behave the same?
> For example, a snippet from an entity:
> {code}
> @Entity
> public class DatesExample implements Serializable {
> 	// This JSR-303 validation will be picked up by Form.
> 	@NotNull
> 	private java.sql.Date aDateMidnight;
> 	// This JSR-303 validation will be picked up by BeanEditForm.
> 	@NotNull
> 	public DateMidnight getADateMidnight() {
> 		return JodaTimeUtil.toDateMidnight(aDateMidnight);
> 	}
> 	public void setADateMidnight(DateMidnight dm) {
> 		this.aDateMidnight = JodaTimeUtil.toSQLDate(dm);
> 	}
> }
> {code}
> I've contributed type coercers in AppModule:
> {code}
>     public static void contributeTypeCoercer(Configuration<CoercionTuple> configuration) {
>        // From java.util.Date to DateMidnight
>         Coercion<java.util.Date, DateMidnight> toDateMidnight = new Coercion<java.util.Date, DateMidnight>() {
>             public DateMidnight coerce(java.util.Date input) {
>                 // TODO - confirm this conversion always works, esp. across timezones
>                 return JodaTimeUtil.toDateMidnight(input);
>             }
>         };
>         configuration.add(new CoercionTuple<>(java.util.Date.class, DateMidnight.class, toDateMidnight));
>         // From DateMidnight to java.util.Date
>         Coercion<DateMidnight, java.util.Date> fromDateMidnight = new Coercion<DateMidnight, java.util.Date>() {
>             public java.util.Date coerce(DateMidnight input) {
>                 // TODO - confirm this conversion always works, esp. across timezones
>                 return JodaTimeUtil.toJavaDate(input);
>             }
>         };
>         configuration.add(new CoercionTuple<>(DateMidnight.class, java.util.Date.class, fromDateMidnight));
>     }
> {code}
> and I've contributed an editor:
> {code}
>     public static void contributeBeanBlockSource(Configuration<BeanBlockContribution> configuration) {
>         configuration.add(new EditBlockContribution("dateMidnight", "infra/AppPropertyEditBlocks", "dateMidnight"));
>     }
> {code}
> Here is the editor:
> {code}
> <t:container xml:space="default" xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd">
>     <t:block id="dateMidnight">
>         <t:label for="dateMidnight"/>
>         <input t:id="dateMidnight" t:type="DateField" value="context.propertyValue" label="prop:context.label" 
>             format="prop:dateInputFormat" translate="prop:dateMidnightTranslator" validate="prop:dateMidnightValidator"

>     public FieldTranslator<?> getDateMidnightTranslator() {
>         return context.getTranslator(dateMidnight);
>     }
