Re: Roller (atom) app - Propono

[Ady Das OToole]

I debugged the error to this line in
...propono.atom.client.ClientWorkspace parseWorkspaceElement(Element 
element){}
Element titleElem = element.getChild("title", AtomService.ATOM_FORMAT);
//Ady comments -> AtomService.ATOM_FORMAT = [Namespace: prefix "atom" is 
mapped to URI "http://www.w3.org/2005/Atom";]
//Ady comments -> titleElem = null
setTitle(titleElem.getText()); //<- the exception is here




java.lang.NullPointerException

Do you have a stack trace for that NPE?

So I'm trying to use the ClientAtomService hooked up to my Roller app
feed and I get a null pointer exception in the Propono code when I try
to do the following:
 ClientAtomService service = AtomClientFactory.getAtomService(endpoint,
username, password);

Looking at my app feed I see the following, which is different from the
example of Roller app feeds that I  see on the web (the "app:" prefix on
the nodes). Anyway, I don't see how that would cause the error - but any
help would be brilliant!

(And thanks Dave for sorting out my app feed)
