Hi,

Is it possible to somehow use validation groups to have different validation for different JSF actions?

I have the case where I want stuff in fields stored away in the model (and therefore validated) when I use command links from a datatable to switch between entities I edit. But how can I handle the "new entity" case where all my fields are blank when I click a command link? I'd prefer not having to write all built-in-constraints to versions that take into account e.g. the entity ID.

I think groups is the way forward. You could have a Edit group and a New group. Depending on your action you can then validate the appropriate group.

It's the "depending on your action"-part which is tricky because how can I do that while still maintaining the automatic connection to the JSF controls? Sure I could do different validation in different actions but then I had to manually bind back the different validation messages to the correct JSF controls, right? (and make sure that no automatic validation is done in the JSF layer)

Tack på förhand,

Unfortunately, I am not so familiar with JSF and how exactly Bean Validation gets integrated. This seems to be more a question for a JSF forum. Have you tried there.

If you find a solution it would be great if you could post it here as well ;-)

Thanks. Posted here but the forum didn't appear that active.
