             Summary: Allow file browser dialog for processor properties fields 
which need a local path
                 Key: NIFI-3806
                 URL: https://issues.apache.org/jira/browse/NIFI-3806
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core UI
    Affects Versions: 1.2.0
            Reporter: Andy LoPresto


When populating local file system paths in processor/reporting task/controller 
service properties, it would be helpful to provide a native file browser dialog 
to allow navigation through the file system. However, I do not propose 
completely replacing the plaintext field with this, as some people may have 
copied & pasted or wish to type the path (especially when dealing with hidden 
or masked files/filetypes). 

I believe that a special "browse" button could be placed in the expanded pane 
once focus is given to allow for navigation and populate a hidden {{<input 
type="file" />}} field, from which the value is extracted to the visible 
plaintext field. (See for example [Kloudless File 
Explorer|https://github.com/Kloudless/file-explorer].)

If this isn't feasible, please indicate and ignore this issue.
