Yves Senn commented on STS-737:
-------------------------------
This would solve to forbidden jump problem but it would not solve everything. I
think we should tell stripes the order of our eventHandlers in Wizard
ActionBeans. This has multiple advantages:
- You can prevent the user from jumping inside the form. Stripes can make sure
that the user passes the form exactly as the developer intended.
- You can allow "backward navigation" without validation errors. This problem
is currently not solved and you have to make a workaround.
- The order of EventHandlers is also interesting for application logic. You
will easily be able to create process bars and other navigation bars.

> Components: Validation
> Reporter: Yves Senn

> We have a multi-page form, that the user needs to fill step by step and
> submit the order at the end. We currently use @Wizard for these kind of forms
> and noticed that it is possible to just enter the data on the first page,
> manipulate the name="" Attribute of the submit button and jump straight to
> the last page. Stripes has no way of detecting that several form pages were
> skipped since the field names never get written to the __fp hidden field.
> I think it should be possible to define an order for the eventHandlers. Then
> stripes can make sure that the eventHandler for step3 gets called after
> step2. With such a mechanism we can guarantee that the user has passed all
> steps when he reaches the end of the wizard. I also think that it should be
> possible to annotate an eventHandler to perform all validations and ignore
> the values in __fp. This way we can make sure that risky actions like sending
> an order or saving the record have all values present.
> To illustrate what I am thinking about I created an example Gist with the
> eventHandler order: https://gist.github.com/1072357cbedbcbf0f587
