Hi Axel,
If I see it right
ParserTextBlocksHandler.notifyModelElementResolvedOutOfContext should be
called after the DelayedReference has been resolved. Which also should
have resulted in adding the element to the specified feature "revenues".
Are you sure that revenues has set "containment = true"? In the current
version in the repository this is false. Therefore, no resource will be
set on that object.
Cheers,
Thomas

[furcas-discussion] NPE during
ParserTextBlocksHandler.notifyModelElementResolvedOutOfContext
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?
