Validation Error: Value is not valid

Question

I have a problem with a p:selectOneMenu, no matter what I do I cannot get JSF to call the setter on the JPA entity. JSF validation fails with this message:

Answer 1

This can be a Converter Issue or else DTO issue. Try to solve this, by adding hashCode() and equals() methods in your object DTO; In the above scenario you can generate these methods within the Location object class which indicate as the 'DTO' here.

Example:

@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + (int) (id ^ (id >>> 32));
    return result;
}

@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    Location other = (Location) obj;
    if (id != other.id)
        return false;
    return true;
}

• Please note that the above example is for an 'id' of type 'long'.
