> take a component with a lazy entry:
> DeployApiEndpoint extends AlpineEndpoint {
>     pivotHandler TBD;
>     handlers [
>       StatsHandler:classname,
>       LogCurrentMessageHandler:classname,
>       AddressHandler:classname,
>       MustUnderstandChecker:classname,
>       LAZY pivotHandler:classname,
>       LogCurrentMessageHandler:classname
>     ];
> This used to work, but now it has stopped; I get an unresolved reference  LogCurrentMessageHandler:classname;
> A dump of the component state during resolution shows this
>  
> LAZY APPLY {sfFunctionClass "org.smartfrog.sfcore.languages.sf.functions.Vector";
> unique4951 "org.smartfrog.services.deployapi.transport.endpoints.alpine.StatsHandler";
> unique4952 "org.smartfrog.projects.alpine.handlers.LogCurrentMessageHandler";
> unique4953 "org.smartfrog.projects.alpine.handlers.AddressHandler";
> unique4954 "org.smartfrog.projects.alpine.handlers.MustUnderstandChecker";
> unique4955 LAZY pivotHandler:classname;
> unique4956 LogCurrentMessageHandler:classname;
> }
> If you take away the LAZY element in the list, all works. Somehow, the moment
> one lazy ref is hit, all following references are deferred, even when they
> should not be. If you add more references, all of them stay unresolved.
> LAZY APPLY {sfFunctionClass "org.smartfrog.sfcore.languages.sf.functions.Vector";
> unique4951 "org.smartfrog.services.deployapi.transport.endpoints.alpine.StatsHandler";
> unique4952 "org.smartfrog.projects.alpine.handlers.LogCurrentMessageHandler";
> unique4953 "org.smartfrog.projects.alpine.handlers.AddressHandler";
> unique4954 "org.smartfrog.projects.alpine.handlers.MustUnderstandChecker";
> unique4955 LAZY pivotHandler:classname;
> unique4956 LogCurrentMessageHandler:classname;
> unique4957 MustUnderstandChecker:classname;
> }
> There is no workaround other than "dont have any non lazy elements in the list after the first LAZY element"
