[jira] [Created] (NIFI-3733) StandardValidationContext may use
wrong default value for PropertyDescriptor if
getSupportedPropertyDescriptors returns a modified version of the
Descriptor.
Mark Payne created NIFI-3733:
--------------------------------
Summary: StandardValidationContext may use wrong default value for PropertyDescriptor if getSupportedPropertyDescriptors returns a modified version of the Descriptor.
Key: NIFI-3733
URL: https://issues.apache.org/jira/browse/NIFI-3733
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
If a component overrides the getSupportedPropertyDescriptors() and then returns something like:
{code}
new PropertyDescriptor.Builder().fromPropertyDescriptor(MY_DESCRIPTOR).defaultValue("hello").build()
{code}
Then when StandardValidationContext.getProperty(MY_DESCRIPTOR).getValue() is called, if no value has been explicitly set for MY_DESCRIPTOR, then the default value that will be used is that of MY_DESCRIPTOR instead of the descriptor returned by getSupportedPropertyDescriptors(). We should instead be using the default value returned by the descriptor in getSupportedPropertyDescriptors().
