Hello,
when I go back to the previous page with the browsers back button and click on

How can I validate a unique constraint with Wicket? Because only the value of
an input field is passed to onValidate(IValidatable validatable), there is no
chance to check if this value belongs to a specific object to update or if it
would violate a unique constraint when creating a new object.
One line was missing in the first constructor. Here is the corrected
constructor:
public EntityModel(T entity)
{
this.entity = entity;
entityClass = entity.getClass();
entityId = getEntityId();
