> I try to use an expression language in a python processor. It works pretty fine, but when I use something like "${my_attribute}_foo_bar" (where "my_attribute" has the value "hello") as the property value, everything after the expression is cut. Just "hello" is shown. If I use a parameter from the context like "#\{my_attribute}_foo_bar", it works and the value is "hello_foo_bar". I was wondering, if I am doing something wrong. But I found the [WritePropertyToFlowFile|https://github.com/apache/nifi/blob/rel/nifi-2.9.0/nifi-extension-bundles/nifi-py4j-extension-bundle/nifi-python-test-extensions/src/main/resources/extensions/WritePropertyToFlowFile.py] processor and tried it. It shows the same behaviour. 
> It can be workarounded with "${my_attribute:append('_foo_bar')}".
