[furcas-discussion] NPE during ParserTextBlocksHandler.notifyModelElementResolvedOutOfContext

[Uhl, Axel]

Hi,

I'm getting the below NPE while parsing the text

					"article{ Shrt, \"John Doe\"}" +
                             "article{ Medium, \"John Doe\"}" +
                             "article{ LongLongLong, \"Jane Doll\"}" +
                             "author = \"John Doe\"." +
                             "author = \"Jane Doll\"."

for the mapping attached. The offending object is a RevenueLedger object for the "Shrt" article. The article reference for the RevenueLedger seems properly set. However, it isn't (yet?) entered into its supposed container object (should be the Author object for "John Doe"). This leads to a problem during identifying its resource set because its resource is determined as null.

Now I'm not sure if at this point in time during reference resolution the RevenueLedger object should already be hooked up with its container. If that can't be guaranteed at this point then the logic in notifyModelElementResolvedOutOfContext probably has to be considered a bug.

Suggestions?
