SysML Blocks Generalization of Flow Properties direction problem

[PeterHeintz]

I have a SysML Super Block (interfaceBlock) defining a Flow Property with direction “out”. From this Super Block I derive a Sub Block by Generalization. For the Sub Block I called Structural Elements… to get the Flow Property in the Sub Block as well.
This works, but the direction of the Flow Property of the Sub Block is set to “inout” rather than to “out” as defined in the Super Block. Due to the fact that the Flow Property in the Sub Block is read only the direction cannot be changed.

I can't quite follow your issue and I notice nobody has replied.  Perhaps if I show how I'm trying (and failing) to reproduce and understand your scenario we'll get this thread moving.

In EA 12.1 Sys Eng Ed...
I create a SysML 1.4 Block Definition Diagram.
On that diagram I add a valueType (myType) and an interfaceBlock (myIblk).
In the interfaceBlock I create an out flowProperty of type myType.

I then add both a block and an interfaceBlock (I'm not sure which you're using) and add a generalisation connecter between them and the first block, myIblk (with the arrow at the first block's end).

If I use right-click, Structural Elements, on the two new blocks the flowProperty is shown, in the compartment of the child blocks, as out, not inout as you describe.

However, via the Properties dialog for the two new flowProperties, in the Tags tab, I see inout shown.


Is this what you're doing Peter?  Does my scenario demonstrate your issue?

[PeterHeintz]

Hello ChB,
yes, that is he problem I have.
I seems that when the structural elements are created the direction is set to a default value inout rather than to the value of the used in myIblk.

Have you logged it as a bug to Sparx?

[PeterHeintz]

As I remember yes.
But I did not find any response from Sparx in my mailbox.
So I will post it again.

I verified that this is solved latest with build 1230.
