--------------------------------
[~mcgilman] Patch attached, I believe I was accurately recreating your scenario
with the test processor. Please let me know if this fix doesn't solve your
problem.
See:
[Here|https://github.com/apache/incubator-nifi/blob/NIFI-632/nifi/nifi-external/nifi-example-bundle/nifi-nifi-example-processors/src/main/java/org/apache/nifi/processors/WriteResourceToStream.java#L54-L67]
[~mcgilman] and [~markap14] and anyone else,
I'm setting/Unsetting a NarThreadContextLoader within the DocGenerator. Does
this seem reasonable to you? Is there a better way?
See:
[Here|https://github.com/apache/incubator-nifi/blob/NIFI-632/nifi/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-documentation/src/main/java/org/apache/nifi/documentation/DocGenerator.java#L73-L91]
Also, I create an "example.nar", and the compiled artifact lives in
[nifi-documentation/src/test/test/resources/example.nar|https://github.com/apache/incubator-nifi/blob/NIFI-632/nifi/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-documentation/src/test/resources/lib/example.nar].
It's source lives in
[nifi-externals|https://github.com/apache/incubator-nifi/tree/NIFI-632/nifi/nifi-external/nifi-example-bundle/nifi-nifi-example-processors].
I didn't think it was a good idea to have the nifi-documentation artifact
depend directly on the nifi-external artifact. Was worried about getting into
a circular dependency issue. I never actually tried it, so I don't know if it
would actually be a problem. Thoughts?

> When auto generating component documentation the NarThreadContextClassLoader
> needs to be set in case the component attempts to load anything off of its
> classpath. Without this, the documentation generation fails.
