It works and is tested; perhaps there's a bug when the property being
persisted is inside a component and not a page (but I really doubt it).

Thanks Howard. I figured I didn't need it on the currentMessage field,
but I didn't want the flex response from someone saying I should try
adding it. ;-)
Either way, the "messages" field is still sticking around past a single
page load.
The pertinent java code that uses it is:
@Component
private Messages messages;
Object onActionFromDownloadDistrict(String districtId) {
messages.addMessage("Last successful download: District " +
districtId);
return null;
}
And of course the html:
<t:messages/>
Anything else I'm missing? Is flash persistence available in 5.0.4?

You don't need the @Meta, you can:
@Persist("flash")
private List<String> messages = new ArrayList<String>();
Also, you don't need the @Persist on the currentMessage field.
