Child diagram does not show Activity Diagram Frame

[DennyRetired]

Has anyone found a fix to a child Activity Diagram frame not being shown on screen? Various approaches include right click on area in diagram and select show frame. There are some other approaches found but none work.  The frame is needed to attach Activity Parameter for Object flow in/out of the diagram.

Note that I am using Sparx EA version 17.

You wnat to have a SysML activity diagram, right?
Unfortunatally EA creates a UML activity diagram under an SysML activity.
To fix that, select the diagram in the project browser, do to Design/Diagram/Options and selcet “Change Type…” to change the type to an SysML activity diagram.
