AbstractWizardFormController and multiple formBackingObjects class, guess, multiple, property, problem

amy

I have looked through other postings and haven't really got a handle on this (I guess I'm hoping for specifics...).

I am intending to have an AbstractWizardFormController that takes the list of pages from an applicationContext.xml file that is external to the application's EAR...this shouldn't be a problem (I hope/anticipate). For exampleCode:
lt;bean id=quot;myWizardFormControllerquot;
class=quot;MyWizardFormControllerquot;gt; lt;property name=quot;myPagesquot;gt;   lt;listgt;     lt;bean class=quot;web.scripts.Pagequot;gt;       lt;property name=quot;viewquot; value=quot;addressCheckquot; /gt;       lt;property name=quot;validatorquot;         value=quot;web.scripts.AddressCheckValidatorquot; /gt;       lt;property name=quot;formBeanquot;         value=quot;web.scripts.AddressCheckFormBeanquot; /gt;     lt;/beangt;     lt;bean class=quot;web.scripts.Pagequot;gt;       lt;property name=quot;viewquot; value=quot;namePhoneCheckquot; /gt;       lt;property name=quot;validatorquot;         value=quot;web.scripts.NamePhoneCheckValidatorquot; /gt;       lt;property name=quot;formBeanquot;         value=quot;web.scripts.NamePhoneFormBeanquot; /gt;     lt;/beangt;     lt;bean class=quot;web.scripts.Pagequot;gt;       lt;property name=quot;viewquot; value=quot;troubleCallTypequot; /gt;       lt;property name=quot;validatorquot;gt;lt;null /gt;lt;/propertygt;       lt;property name=quot;formBeanquot;gt;lt;null /gt;lt;/propertygt;     lt;/beangt;
...
...this should work OK to configure the views (via a setMyPages() method eventually calling setPages()).

BUT...

As far as I can see, AbstractWizardFormController really likes to have a single controller (form bean) with set/get methods for ALL properties and it binds the subset of the available properties as it needs.

Clearly, I can't do this in this situation.

Has anyone quot;out there in Spring landquot; done this before? Tips/code would be MUCH appreciated.

I don't really want to have to move to Spring Web Flow...it seems a little 'heavyweight' for the task at hand.

Just wondering: perhaps I could use a dynamic proxy for this situation?

Make a proxy that dynamically implements the 'or' of all the individual properties and dispatches to the individual underlying classes as required.

I'm not keen on this but I _am_ seeking feedback, after all...

You could make a Wrapper object that contained instances of all the objects you would like to get back from the pages.Code:
public class MyWrapper {

private AddressCheckFormBean address;
private NamePhoneFormBean name;

/* Getters and Setters */

}Thanks for the suggestion.

Don't want to do this--as it is shown--'cos I don't know exactly which views I will have until the controller is configured...makes creating a wrapper a bit tricky.

This is sort of what I was thinking of doing with the dynamic proxy idea.

Cheers,

Here is the result:
