I get the same exception on a Graph. Were you able to resolve the issue?
I was having this same problem after having created a demo application that displays a
graph of the employee salary data using Oracle's XE built-in HR database.
I am using Jdeveloper 184.108.40.206.0.
After some experimenting, I found I could eliminate the error by changing the setting of
CacheResults in the Iterator from the default <true> to false. Granted, this will affect performance, but
it is a work-around. I think that the error is that the data from element is not being stored anywhere for
the graph element to pick up (this may be due to partial-page rendering (ppr), but I am not sure.)
Open your .jspx file in the editor. Select the graph component. Click on the Bindings tab at the bottom.
You should see a binding between a graph component (under Bindings) to an Iterator (Executable) to
a Data Control element.
Click on the Iterator, and under Advanced, set the CacheResults to false and rerun the application.
Hope this helps.
Awesome investigation and good suggestion.
Ran into EXACT same problem and changing the CacheResults to false solves the null pointer exception.
