             Summary: Controller Services Validation Tooltips Not Working
                 Key: NIFI-3465
                 URL: https://issues.apache.org/jira/browse/NIFI-3465
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core UI
    Affects Versions: 1.2.0
            Reporter: James Wing

The tooltips for Controller Services validation errors are not working in 
recent master builds.  Repro steps:

# Open the Process Group Configuration dialog
# Select the Controller Services tab
# Add a new Controller Service
# Select AWSCredentialsProviderControllerService and click Add
# Make it invalid, for example:
#* Edit the AWSCredentialsProviderControllerService
#* In Properties, type something into the Access Key field - "foo"
#* Click Apply to save and close
#* Service should now be invalid
# Hover over the validation warning icon in the left column

I believe the problem was introduced with the jQuery upgrade in 
[6170f64|https://github.com/apache/nifi/commit/6170f6442ed45dd084617cb4f39085640f49ebc5],
 but I'm not good enough with the UI to tell how it's broken.  

There is a workaround - validation errors are coming from the server, and you 
can see them in the network section of the browser dev tools.
