How do I deal with exceptions when using the SAF?

[ccanning]

I have to override the standard persistence mechanisms to get my persistence to work, but that requires some exceptions to be thrown and some messages to be sent back to the user. How do I deal with this in the SAF context? Does it require me to make my exceptions RuntimeExceptions? Is there a way to tie business level validation into the regular validation mechanisms? Thanks.

You can do stuff like:

public String persist()
 {
 if ( ..... ) {
 return super.persist();
 }
 else {
 FacesMessages.instance().add("can't persist");
 return null;
 }
 }

Is that OK?

Thanks. That was what I was using while waiting for an answer.
