John Moehrke (Mar 16 2016 at 15:19):
I have tried to resolve this... days have gone by... What stupid thing did I do? Surely someone has figured out what generally causes the build to throw nothing more informative than NullPointerException????
Lloyd McKenzie (Mar 16 2016 at 15:45):
You've tried validating that instance against schema and schematron? (the "built" version of it)?
John Moehrke (Mar 16 2016 at 20:02):
guide me... what should I do? I have eyeballed it, yes. It is not complex. (I am making an alternative ImagingObjectSelection for the imaging wg to evaluate an alternative...
Grahame Grieve (Mar 16 2016 at 20:48):
there's something wrong with the registration of the example, not the example itself
Grahame Grieve (Mar 16 2016 at 20:49):
but it's not obvious to me what that would be
John Moehrke (Mar 17 2016 at 02:13):
what I have done is made a copy of ImagingObjectSelection, and made some minor optional additions of elements.... so is there something I should have done to the example beyond fixing the xsd it pulls in, and the start/end element name???
Grahame Grieve (Mar 17 2016 at 02:20):
why did you change the start/end element name?
John Moehrke (Mar 17 2016 at 11:54):
I made a new resource starting from ImagingObjectSelection... called it ImagingExcerpt
John Moehrke (Mar 18 2016 at 13:45):
I just abandoned everything i had done... and started fresh following to the letter the instructions http://wiki.hl7.org/index.php?title=FHIR_Guide_to_Authoring_Resources I end up with the same null pointer exception error
Keith Boone (Mar 18 2016 at 16:03):
He changed the resource name ... he's showing an alternative way to implement it.
Grahame Grieve (Mar 18 2016 at 18:17):
it seems my earlier comment didn't make it into this topic. It looks to me as though you have not added the resource to heirarchy.xml
John Moehrke (Mar 18 2016 at 19:17):
that is not it.. I did add it to heirarchy.xml
Grahame Grieve (Mar 18 2016 at 19:21):
ok. update and try again then please
Grahame Grieve (Mar 18 2016 at 19:22):
I've tried to improve the error mesage
John Moehrke (Mar 18 2016 at 19:37):
building.....

John Moehrke (Mar 18 2016 at 19:53):
why does Questionnaire get to FAIL ME!!! okay, more specifically, what do I need to do to get questionnaire to be happy?
Paul Knapp (Mar 18 2016 at 19:54):
Try doing an update then run again.
Paul Knapp (Mar 18 2016 at 19:55):
oh and to a clean after the update, before the publish.
John Moehrke (Mar 18 2016 at 19:56):
paul, I hae done that many many times.
Grahame Grieve (Mar 18 2016 at 19:57):
ImagingExcerpt is a different name to your type?
John Moehrke (Mar 18 2016 at 19:57):
that is the Resource i am creating
Paul Knapp (Mar 18 2016 at 19:58):
It is your resource that has the error.
John Moehrke (Mar 18 2016 at 19:58):
I figure... but where?
Grahame Grieve (Mar 18 2016 at 20:01):
beats me. send me your heitarchy.xml. All the evidence from looking at the code says that the problem is there
Paul Knapp (Mar 18 2016 at 20:01):
Are you missing any closing tags or /> in the example?
John Moehrke (Mar 18 2016 at 20:02):
looked again at hierarchy.... spelling mistake... building again
Grahame Grieve (Mar 18 2016 at 20:03):
I thought there was an explicit error if it wasn't in heirarchy.xml. I'll check
John Moehrke (Mar 18 2016 at 20:51):
build successful -- 34 minutes
Grahame Grieve (Mar 18 2016 at 20:56):
great
Keith Boone (Mar 19 2016 at 07:00):
Misspelling in hierarchy.xml.
Keith Boone (Mar 19 2016 at 07:03):
Grahame, it would be extraordinarily helpful to me for diagnosing these sorts of issues if you would provide a short explanation of the reason for each line that has to be added to some file to add a new resource. e.g., You add the resource name to hierarchy.xml so that we can assign numbers to each "page" in the build.
Keith Boone (Mar 19 2016 at 07:03):
That way, when we get errors related to a particular module (i.e., breadcrumbmanager), we can figure out what file might be the source of the problem. This will also help us lower our bus number.
Grahame Grieve (Mar 19 2016 at 07:21):
it's probably a good idea, but where would we do that? on the wiki where it already is, or somewhere else where no one looks?
John Moehrke (Mar 19 2016 at 18:24):
so the wiki was correct... And you have made the build more clear on this error, right? Therefore I think enough is done for now. Clearly better tooling is always better; but we need to be realistic about where effort is spent. The root cause of this issue was my fat-fingers.
Grahame Grieve (Mar 19 2016 at 20:03):
yes I made the actual error explicit now
John Moehrke (Mar 19 2016 at 21:22):
Meaning, the error says: "Did you do a John, and misspell your Resource name?"
Grahame Grieve (Mar 19 2016 at 21:33):
No, it says, "John, check your spelling in your file". It's always helpful to be specific about the wrong thing in error messages
Keith Boone (Mar 19 2016 at 22:54):
I think in the Wiki, which both John and I read before creating a new resource.
