Description

Writing and testing expressions is not a great experience for Nifi users. In the UI for a processor configuration it is basically typing text in a small text box....

Nifi should have a ui for authoring expression language statements.

• This UI should be available when editing a property that supports EL
• This UI should be available stand alone from the main UI menu
• This property should 'discover' and display the referenced variables /attribute names and allow setting values for them
• This UI should allow execution of the statement, with the variables/attributes/values as configured in the UI to test the results
