Matt, Great news! I was able to successfully test the changes you made to address the import template issue. I do not know what other verification is needed for your PR to be approved, but after building NIFI 1.2.0-SNAPSHOT with your changes from NIFI-3207, the issue is resolved.
Thanks. Rick. On Thu, Dec 15, 2016 at 1:43 PM Matt Gilman <[email protected]> wrote: > Rick, > > Here's my proposed solution for the template upload issue [1].
