> 	I'm trying to use a reference to an external feed with the org.apache.tuscany.sca.data.collection.Collection interface, but I'm running into problems. The new feed-aggregator tests display this issue. 
> The problems show up in AtomBindingUtil.entry(...)
>  if (itemClassType.getPhysical() == Item.class) {       	
>         String key = feedEntry.getId().toString();
>       ...     
> The code doesn't get into this block of code because the physical type is java.lang.Object ( this originates from the return type of Collection.get() which is Object -- this is set in the reference binding provider's createInvoker method) If I change the code to force it to go through this block, things work OK.
> In the 'else' block that the code goes through instead, the following lines will cause the method to always return a null entry:
>                if (feedEntry.getContentElement().getElements().size() == 0) {
>                         return null;
>                 }
> The <content> element of the returned feed is just some HTML, so there are no subelements.
> My assumption is that the first block of code is intended to handle this case, but I'm not sure how this code should correctly identify that we are using org.apache.tuscany.sca.data.collection.Item
