----------------------------------------

>From IRC:

(09:51:34 PM) stuartdouglas: really EntityConverter can be replaced with a generic conversation scoped convertre
(09:52:13 PM) stuartdouglas: basically you have a conversation scoped components with a map<String, Object>
(09:52:29 PM) stuartdouglas: when you convert to a String you generate a arbitrary string id and store it
(09:52:39 PM) stuartdouglas: to convert back you just do a map lookup
(09:52:52 PM) stuartdouglas: so you can convert anything as long as you have a conversation active
(09:57:40 PM) bleathem: one could use the view scope, no?
(09:57:48 PM) bleathem: you always post back to the same page
(09:57:49 PM) stuartdouglas: yes, any long lived scope would work

> class Foo {
>   Bar bar;
>   // Getters and setters
>   List<Bar> bars;
>   // Getters and setters
> }
> <h:selectOneMenu value="#{foo.bar}" >
>   <f:selectItems value="#{foo.bars}" var="bar" itemLabel="#{bar.label}" itemValue="#{bar}" />
>   <s:convertEntity /> || <s:convertObject />
> </h:selectOneMenu>
> I want to be able to have my setter/getter reference an object and not write the boilerplate for converting to/from a string.
> I also want to reference a managed entity, and have that managed entity set back into the setter so I can see the changes updated in the database with no boilerplate, and avoid LIEs.
