Flow Properties compartment not available

[PeteC]

If I create a SysML Block Definition diagram, add a Block and to the block add a Flow Property then the item appears on the block in the "flow properties" compartment. The compartment can be toggled from the diagram properties to be visible or not.

If I drop a link to the same block on my custom diagram, the flow properties compartment cannot be displayed on the block; it does not even appear in the list of available compartments in the Show Compartments section of the diagram properties.

What do I need to add to my custom diagram definition in my MDG for it to work the same as the SysML diagrams?

Right now, the only way to do that is to use a view specification to add an available view to the original SysML diagram.

So how would I do that?

I already have a View Specification that extends my custom diagram and exposes my desired elements and relationships.

Adding an extension from my existing View Specification to SysML1.4::BlockDefinition only results in adding my defined View Specification to a SysML Block Definition diagram, not adding the ability to display the "flow properties" compartment on elements on my custom diagram. What it did is what I expected the way I defined it from how I understood View Specifications to work.

I can't see anything else in the documentation explaining how to achieve what I wanted. I am wondering if from what you are suggesting I need to related my View Specification to SysML1.4::BlockDefinition in a different way.

Then you have it working.

It does not change your diagram definition. It's completely unrelated.

No. You just need to use the view specification from the SysML block diagram.

OK, but I was trying to get the flow properties compartment to appear on my custom diagram type, not a SysML diagram.

[Eve]

The flow properties compartment is specified by the SysML diagram types. You can't inherit from them, so the only way to have a customized diagram using them is a view specification extending the original SysML diagram.

That means, you need to choose between a completely new diagram type or having the SysML functionality.
