Separating model and seam

[jochus.jochenhebbrecht.hotmail.com]

Hi,

I'm currently throwing a validation message to my view layer using the Hibernate Validation framework (validation is made on my model/object using annotations):

     @NotEmpty
     @Pattern(regex = "[0-9_\\-/\\. ]{1,}", message = "{biller.details.field.incorrect.characters}")
     private String dummyString;

The messages is surrounded with { } so Seam will localize the key with his i18n resource bundle.

This works fine, but ... if you think a step further, and look more to the architecture, you can see you are making your model dependent of Seam. Imagine your model should be picked up in a Spring application, the messages with { } will not be working any longer ...

So, how can we use the Seam resource bundle from the Hibernate Validation framework without being dependent on Seam?

The messages within braces / message interpolation depends not necessarily on Seam. You only need Seam in this case for EL-Expression evaluation. For further information, consider reading the according hibernate validator manual and Seam JSF form validation manual.

Hope that helps!

Thomas,

Thnx for your reply. I've read the pages you provided. So there seems to be a difference between:

message={...}

... and ...

message=#{...}

The last one is using the Seam resource bundle. The first one needs a EL-expression evaluator. But that EL-expression evaluator can be anything.

Is that correct?
