Hi Konstantin,

Sorry for appearing stupid but I still don't see how attributes can help me.

here is the original situation:

1) Form is submitted and form values are set into request *parameters*
2) DatabaseAddAction reads request *parameters* and puts them into database.

But I need to manipulate the parameters first so I thought I'd put an action
between the form and the DatabaseAddAction which alters the request
parameters:

1) Form values set into request *parameters*

2) My action reads values from request *parameters*

I cannot set new values back into request parameters

If I set the new values into request attributes then the DatabaseAddAction
ignores these and reads the original values from the request parameters.

If I set the new values into sitemap parameters then the DatabaseAddAction
ignores these and reads the original values from the request parameters.

3) DatabaseAddAction reads request *parameters*

Request attributes are different from request parameters aren't they?

Thanks for your patience,

Chris
