-------------------------------------
Summary: StandardParameterContext.parameters map may contain
inconsistent key and value
Key: NIFI-9496
URL: https://issues.apache.org/jira/browse/NIFI-9496
Project: Apache NiFi
Issue Type: Improvement
Reporter: Peter Turcsanyi
{{StandardParameterContext.parameters}} map stores {{ParameterDescriptor}}
(key) to {{Parameter}} (value). The {{Parameter}} also has a reference to its
{{{}ParameterDescriptor{}}}.
When the {{Parameter}} is updated (e.g. its description is changed), the
{{Parameter}} will reference the new {{ParameterDescriptor}} but the map key
will still be the old one (because {{ParameterDescriptor.equals()}} is based on
the {{name}} field only).
This is an inconsistent data structure that may lead to bugs.
Using simple String key with {{ParameterDescriptor.name}} could be a solution.
To replicate the issue:
- debug {{TestStandardParameterContext.testUpdateDescription()}} and stop at
this line:
[https://github.com/apache/nifi/blob/7d8f99a1f41bb1806706c5db857f109c5d7b4e7f/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-framework-components/src/test/java/org/apache/nifi/parameter/TestStandardParameterContext.java#L128]
- check the key/value in {{context.parameters}}
