Re: [jira] Resolved: (TUSCANY-1256) NullPointerException when component
reference has target of composite reference
Posted by Simon Nash <na...@hursley.ibm.com>.
I tried this with a new checkout. I made the "deliberate mistake"
in the SCDL, and the test now runs successfully even though there is
a SCDL error.
This is much better than a NullPointerException, but I'm wondering
if it's correct. Shouldn't this be flagged as an error?
