Issue

User is unable to launch a local action inside another local action using the out-of-the-box ProcessAction activity by passing all the required parameters.

Environment

Pega Platform 8.8.5

Steps to Reproduce

1. Launch a local action in a process flow.
2. Launch another local action from the previously launched local action.
3. Observe the behavior. At run time, the local action is not rendered on user interface.

Explanation

Launching a local action inside another local action is not a supported configuration. Modal/Overlay can be launched from client side using a button and an action set. It is not possible to directly call ProcessAction activity. 

Solution

Launching a modal from another modal is not supported. Launching an overlay from another overlay is not supported. However, you can launch overlay from modal dialog and vice versa.
