Re: Struts2 Validation Problem - validation errors not being cleared when corrected!

[Murray Furtado <mu...@googlemail.com>]

Hehe, I've just resolved my own issue!
The problem was my spring configuration. I needed to
specify scope="prototype" on each of my Struts 2 Action declarations.
Singleton actions were being created and thus previous field errors were
being carried over between requests.

I'm surprised this isn't a more common gotcha that should be highlighted in
the documentation.
