Validation for inplaceInput

hdu Apr 14, 2011 4:32 PM

What is the proper way to validate an inplaceInput using Hibernate validation on the bound entity bean. I tried to use Seam's s:validateAll on it but it does not seem to work: the error message does not display after clicking save (the green check mark icon); instead the incorrect value is displayed in view mode (in this case the input exceeds 40 characters), but is not actually updated to the database.

<s:validateAll>
    <rich:inplaceInput id="inplaceInput" value="#{person.name}"/>
    <s:span rendered="#{invalid}">
        <h:message for="inplaceInput" styleClass="errors" />
    </s:span>
</s:validateAll>

@Entity
@Table(name="PERSON")
class Person {
     private String name;

     @Column(name="NAME", length=40)
     @Length(max=40)
     public String getName() {
          return name;
     }
     ...
}

1. Validation for inplaceInput

change h: to rich:message
if not helps try rich:beanValidator in inplace.

and if will not resolve please show complete form code inclusing controls.

Thanks for your reply, Ilya.

Actually, the problem was that I needed to reRender the region around the inplaceInput upon clicking save. That redisplayed the h:message with the error.

I have a similar problem with an inplaceInput inside a dataTable. It seems to skip the PROCESS_VALIDATIONS phase and fails on the INVOKE_APPLICATION phase when performing the action personPage.save which calls personHome.update to update the person.contacts collection. The validation works fine on a non-collection field outside a dataTable, i.e. person.name
