Get adaptive family shape handle points - InvalidOperationException

[Brett_Burling]

In a project I am trying to get all the shape handle points of an adaptive family instance using the following code:

...

Dim r As Reference = UiDocument.Selection.PickObject(ObjectType.Element, "Select element:")
Dim e As Element = Document.GetElement(r.ElementId)

Dim fi As FamilyInstance = TryCast(e, FamilyInstance)
Dim shapeHandlePoints As IList(Of ElementId) = AdaptiveComponentInstanceUtils.GetInstanceShapeHandlePointElementRefIds(fi)

...

If the adaptive family contains both placement points and shape handle points the code works as expected. 

If the family has no placement points and only shape handle points an InvalidOperationException is thrown.

Is this expected? An obvious workaround is to add a placement point to my family but i'd rather not do this.

Dear Brett,

Thank you for your query.

Can you please submit a full minimal reproducible case including a macro to execute in the sample model and detailed steps of what to pick etc. to experience the behaviour you describe?

No prob.

• Revised project attached that contains the macro.
• GIF attached that shows the steps to reproduce the error.

Hope that's clear.

Dear Brett,

Thank you for your update and sample material.

I am unable to open the GIF file:

Can you describe the steps to reproduce the issue in words as well, please?

Thank you!

That's odd works fine on the few computers I tired here (and my phone) anyways steps are as follows...

1. Open the project (attached)  and activate the view called "Level 1". The view contains 2 adaptive component families and text labelling them.

2. Run the macro called "NumberOfAdaptivePoints" and when prompted select the family labelled "Family with adaptive point and two shape handles" the macro executes and a dialog is displayed showing the number of placement points and the number of shape handle points. This is the expected result.

3. Run the macro again but this time select the family labelled "Family with no adaptive point and two shape handles" The macro executes and an exception is thrown at line 37. I was expecting to get a list that contains 2 shape handle element ids.
