I think this is probably a good approach.

> Support Dynamic Forms
> ---------------------

> Key: CLK-638
> URL: https://issues.apache.org/jira/browse/CLK-638
> Project: Click
> Issue Type: New Feature
> Components: core
> Affects Versions: 2.1.0
> Reporter: Bob Schellink
> Assignee: Bob Schellink
> Fix For: 2.2.0
>
>
> One area where Click can improve is supporting dynamic forms. Typical example
> is registering JavaScript events on Fields to submit the Form and then add
> more Fields as the user navigates the Form.
> Couple of reasons make this problematic. Form automatically validates its
> fields. One can switch off this validation but need to keep in mind to switch
> validation back on for non JS submissions.
> The other area which is tricky is that all dynamic fields must be added in
> the Page onInit event in order to be processed properly. One can invoke
> field.bindRequestValue to query the field's value, but bindRequestValue
> doesn't properly check whether or not its parent Form was submitted.
> I propose we add a couple of helper methods to Form and Field to make this
> process smoother eg:
> void field.bind();
> boolean field.bindAndValidate(); <- will return true if the field is valid,
> false otherwise
> form.bindFields();
> boolean form.bindAndValidateFields(); <- will return true if *all* fields are
> valid, false otherwise
