For example you want to create a new record, to instantiate a new form bean you'd perhaps have to save a record to the db, and all this before the user decides what s/he wants to do with it.
niall wrote some classes that could be useful.

I guess your first place to look would be DynaActionForm - this base

DynaValidatorActionForm adds validator support to this.
Perhaps you could extend this class to add your own methods for specifying form properties on the fly.
The key function seems to be initialize(FormBeanConfig) - FormBeanConfig
"represents the configuration information of a <form-bean> element in a
Struts configuration file".
So create a FormBeanConfig object in code to represent the dynamic data you want and then initialize a DynaActionForm with this object.
Add properties to FormBeanConfig with addFormPropertyConfig.
That sounds like a realistic starting point...
Anyone else have any ideas suggestions or corrections?

I have written a very rough website page content management system using Struts and OJB. (The goal being to allow end users to modify content without having to know anything about Struts or the code behind the pages.)
That's working all well and good, but now they want to be able to create forms "on the fly".
I would like to store all of the form components and validation in the database as well, but I'm not sure how to represent that in Struts (since there's no ValidatorActionDatabaseForm).
I would appreciate any advice, tips/techniques, or gotchas that you guys could provide.
