How to listen a event only if instance exists

diegocoronel Dec 28, 2009 4:41 PM

Hi,

Is it possible to have something similar to

@Observes( create = false )

that Seam provides ?

I just want to listen a event only if a instance of that class exists... if not, will it be provided by Seam 3 or is is possible to implement a extension to modify this behaviour ?

public void refreshOnDocumentUpdate(@Observes(receive=IF_EXISTS) @Updated Document doc) { ... }

See section 10.4.3 for more details in the spec
