Steps to Reproduce

1) Configure a Repeat Grid with Expandable Rows using Master-details option. Reference a flow action rule in Detail flow action field.

2) In the Section where the flow action is referenced to, include a button.

3) For the button, add a click Event and associate it to a Local Action.

4) Associate the Local action to a Local Action to launch a Modal Dialog.

5) When the row is expanded and the button is clicked, the modal does not launch as expected and the IndeterminateConditionalException is thrown.

Root Cause

A software use or operation error. 


When using grids, Local Action should not be used. Instead, it is recommended to use the Open Local Action under the List section.
