Yes, in my situation, the converters are all registered by class, so I
cannot call a Converter constructor (or a converter property).
Having a value binding was the best possible compromise -- after all,
I can change the registered managed bean in the config file or in the
code if it came to that. Realistically, my backing bean doesn't
change all that often. My "database-layer backed select item
provider" beans are code-generated and static.

thanx for response and sharing of Your ideas.
i would like to register ma converter and use it on many pages.
but when i hardcode this
#{backingBean.selectItemList}
than obvoiusly my converter is coupled with one specific bean (and
few specific pages - in optimistic case) :/
btw: now im doing it like this:
public class BackingBean{
private List<SelectItem> items;
public List<SelectItem> getItems(){
return items
};
public Converter getConverter(){
return new MyClassConverter(getItems());
}
}
i dont like my solution cause i just dont want to repeat:
public Converter getConverter(){
return new MyClassConverter(getItems());
}
in every bean that backs my combo controls (but it works and is
flexible)
best regards and once again thanks for response
