Custom Action error message

[wiggum]

Hi,

I'm running a custom action that is copying a file to another server, and I'd like to display error messages at the completion of the move as to whether or not the copy succeeded. 

So what's the best way to display a custom message to the user after the completion of a custom action?

Thanks!
Sean

Wanted to post the solution for reference (thanks support!):

FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_INFO, msg, msg);
context.addMessage(null, facesMsg);

This then gets shown in the client via the "a:errors" tag (ignore the name, see browse.jsp as an example).
