------------------------------------
Okay I've made the changes and committed them to a local branch. I need to
follow the directions for getting a PR created. I ran into something that
distracted me from getting this completed in a timely fashion. Brief
description below:
It seems like TestListFile has had a couple different issues filed against it.
It fails for me every time. Anyway I haven't spent enough dedicated time with
it. NIFI-3831 mentions the issue in almost the same way I'm experiencing the
failure.
https://issues.apache.org/jira/browse/NIFI-3831. The method I'm failing on is
filterAge.
Anyway I wanted to provide an update. Will bring it back to what this
particular ticket is focused on.
> Improve documentation regarding PropertyDescriptor name & displayName
> ---------------------------------------------------------------------
>
> Key: NIFI-1795
> URL: https://issues.apache.org/jira/browse/NIFI-1795
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Documentation & Website
> Affects Versions: 0.6.1
> Reporter: Andy LoPresto
> Assignee: Ryan Withers
> Priority: Minor
>
> As evidenced in numerous pull requests, developers are often unaware of the
> behavior of {{PropertyDescriptor}} {{name}} and {{displayName}} attributes.
> Originally, {{name}} existed and served as both the UI display value for the
> processor properties configuration dialog and as the unique identifier when
> writing/reading the properties from file storage. However, a change to the
> {{name}} value after the flow had been persisted could cause issues
> retrieving the value from file storage. Thus, {{displayName}} was introduced
> as the UI display value to allow for backward-compatible updates. The
> documentation does not sufficiently explain this information and can better
> encourage developers to provide both {{name}} and {{displayName}} attributes
> in order to be proactive on flow compatibility and to improve the foundation
> for internationalization and localization of the UI.
