[Pete Muir (JIRA)]

    [ https://jira.jboss.org/browse/SEAMFACES-28?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12534828#action_12534828 ] 

Pete Muir commented on SEAMFACES-28:
------------------------------------

The UID you store should NOT be based on some list order solution, it needs to be based on an ID stored in a map because otherwise if the backing list order changes, the converter fails.

> Given 
> 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.
