Submit Once, Validate Twice -- but how ?

[Frank Schaare <lo...@gmx.de>]

Hi,

just read this article on husted.com and it seems to be good advice.

When the user submits a page, passes validation without errors, is there 
a chance to validate business logic in the action ?

Therefor i need to
- make my validation,
- get an errors object,
- store the error,
- put the errors object in the request and
- return to input page.

Has anyone some sample code / suggestions / articles / sources hoe to 
achieve this ?

Thx....
