Re: [Springframework-rcp-dev] Bean methods that throw exceptions?

[Geoffrey De S. <ge0...@gm...>]

Forms are ussually meant for domain objects or transfer objects.
Just like it's pretty impossible to try to jpa-persist a (heavy) 
business service or DAO instance.

Wouldn't the use case you describe be better off if you
initialize the encodedBody before showing the form?

With kind regards,
Geoffrey De Smet
