Subject Add hidden show capability to sensitive text-area boxes
Date Sun, 12 Feb 2017 08:28:35 GMT

In controller-services, for ex: HiveConnectionPool there is a property
called "Password". One of our clients who use  nifi wish to add the
capability of hidden show (input type="password"). I understand property
list table is dynamically populated using jquery (please correct me if am

Below is what i suggest:

When we mention like below in this case for password property:

public static final PropertyDescriptor DB_PASSWORD = new
            .description("The password for the database user")

i suggest to add

 .hiddenshow(true) (or any other name)

so that frame work can add an jquery and css appropriately to build the
password like hidden show nature: "***********" ( we can even replace the
textarea tag to input type='password> ) only for these cases.

I would like to your views on this..
