selectItems and entities with inheritance
Hello,
I have an abstract entity Feed and two entities that inherit from it, RemoteFeed and AggregatedFeed. I have the following on my page:
<h:selectManyCheckbox value="#{aggregatedFeedMod.selectedFeeds}" layout="pageDirection">
<s:selectItems var="feed" value="#{aggregatedFeedMod.availableFeeds}"
label="#{feed.displayName}" />
<s:convertEntity />
</h:selectManyCheckbox>
where aggregatedFeedMod.availableFeeds is of type List < Feed >; the list contains entities of both subclasses.
Here's the exception I have when I try to display that:

I'm not quite sure if it's a Seam issue, or a JBoss EL/JSF RI issue.
