When deploying a Process Property and configuring a Password Data Type, this is how the Process Property configuration page looks like.
When this Process Property is Extended and you check the Environment Extensions in the Atom Management page, you see that the password is visible even though this should be hidden.
In checking the usage of the Process Property (the screenshot shows this as Netsuite Connections Parameters), you will see multiple processes using this Process Property and these processes will be deployed to the same Environment.
This issue happens when you already have a deployed process with a previous version of the same Process Property in which the Data Type for the Password property is set to String. When you view the deployed components of other processes using the same Process Property (in the screenshot this is named Netsuite Connections Parameters), you will see the following.
When you already have a previous deployment of the same Process Property in which the Data Type for Password property is set to string, this will still be in effect even if you deploy a new process in which the Data Type for the Password property is set to Password.
To resolve this, please re-deploy all processes that are using the same Process Property to make sure that the Data Type for the Password property is set to password. When you have re-deployed all of the processes, you will see the expected view in the Environment Extensions page.
