Dave,
Thanks for the reply.
I've had some success...tinkering...
The following validation annotation seems to work:
@ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE},
fetch=FetchType.EAGER)
@JoinColumn(name = "STATUS")
@ExpressionValidator(message = "Default message", key="validate.status",
expression = "status != null" )
public Status getStatus() {
return status;
}
However, the validation message appears in <s:actionerror /> block, not
nicely next to the field that failed validation as does the other
validators.
I might have expected this if I had specified shortCircut=true, but I
don't. I'm not really sure what the shortCircuit flag is supposed to do.
Is there a way to make the validator work as the @RequiredString
validator where the message appears above the label? Could this be a
bug?
Again, thanks for your help, I really appreciate it.
Cheers!
MG

My first assumption would be that you'd need to have a custom validator,
depending on how Status objects are initialized/created. AFAIK
"required" will only check for nullness.
I'm not sure if a Status object will be created if no status properties
are set, but if it is, then it probably won't work with a simple
"required". If any status properties are set then it definitely
won't--empty string fields aren't null; they're blank.
I'm a little surprised "required" works with your textfields, since
strings normally need a "requiredstring" validator to function properly.
