Our DynamicBean holds java.util.Calendar, not java.util.Date nor java.sql.Date.
We have a persistence framework that converts ResultSet in a collection of DynamicBeans, so our Business layer doesn't use java.sql.Date but Calendar.
We use DynamicBean as DTO from UI (used by DynamicForm) to persistence layer, where we have transformers from DtynamicBean to PersistenceObjects, which are mapped to tables by our persistence framework.
This is a sequence of saving a data in a database: 1) Browser submits a post. 2) Struts populate this parameters to the DynamicBean 3) Action uses (DynamicForm)form).getModel() and passes it to a service (JMX service) 3) the service recives DynamicBean and returns DynamicBean. Uses input DynamicBean to validate rules. 4) the service passes the validated DynamicBean to the persistence layer, where DynamicBean is transformed to Persistence Object. 5) Persistence framework persists this object in the database.

Should java.sql.Date belong in an form bean?

Thanx and regards marco

I previuosly posted a mail to this list asking why DynaForms are called Dynamic if you have to declare them statically in Struts-Config. But there was no answer :(
We created in our project a DynamicBean (previous DynaBean release and
when Struts 1.1 was no available) and extended ActionForm to be a holder of DynamicBean (somethind like this: ((DynamicForm)form).getModel() returns a DynamicBean with all properties.)
So, we add html:text fields to the JSP and these are populated to this
DynamicForm without the need of declaring this property anywhere. And we have optionall Contract asserter to verify properties in a DynamicBean when needed (usually when using DynamicBean as a DTO between Actions and Business delegates)
Cheers. Guillermo.

Can someone PLEASE help?
I need to create a User Interface (in JSP) which presents the user with a number of input fields. The number of input fields is not known until run-time (based on user selections in a previous screens).
The 2 issues I see are: 1. generating the JSP dynamically with the correct number of properties 2. accessing these form fields in the action class.
Normally, form property definitions need to be defined at compile time (whether you use Action Forms or DynaForms)
Ideally, I'd like to use the struts framework to avail of Validator,etc,etc. Also, I would like to use Struts Dyna Forms.
Can anyone advise a suitable approach & sample code?
