You could try a depth-first traversal of subcases.

When visiting the subcase call Work- reopenWorkObject.

This activity also reopens the parent case.

It is essential for a Cover to maintain the correct value for pxCoveredCountOpen.

The depth-first approach resembles an "Undo", i.e., winding back the clock in reverse.

Work- reopenWorkObject should increment is Cover's pxCoveredCountOpen.

Step 13 is Call UnResolveCover. Step 13 in that activity increments pxCoveredCountOpen.

As far as depth-first looping, note the logic in the pxIsInTree Function. This function is told to look in a list, e.g., pxResults, looking for some value within some particular property.

If the pxResults pagelist contains a property named ".pxResults", the logic pushes that ClipboardProperty onto the stack and keeps looking to see if there us another pxResults pagelist at a deeper level.

Eventually the answer is "no".  At that point you decide what to do since you have hit "bottom".

Instead of a PageList you would have a ValueList named pxCoveredInsKeys.

When you hit bottom, you could try calling reopenWorkObject but that would be complex to do inside java.

What you could do instead is start with an empty ValueList and simply add each pzInsKey to it.

When you exit the java step you have a flatted ValueList of pzInsKeys to iterate.

For each pzInsKey in the ValueList Obj-Open-By-Handle as "pyWorkPage" then call reopenWorkObject passing "pyWorkPage" as the value for param.WorkPage.
