Overriding connection between nested nodes

[pronline2013]

I have an issue with the syntax of overriding connections between nested nodes.

The sample code below shows a number of nested nodes, with a connection between the innermost nodes.

direction: right

root
root.level_1_A
root.level_1_B
root.level_1_A.container_1
root.level_1_B.container_2

root.level_1_A.container_1 -- root.level_1_B.container_2

Based on the documentation, I was under the impression that the following code would remove the connection between node root.level_1_A.container_1 and node root.level_1_B.container_2.

(root.level_1_A.container_1 -- root.level_1_B.container_2)[0]: null

However, this doesn't seem to be working. Is there anything I would need to do differently to be able to remove the connection? Any other syntax that I would need to use in this case?

Many thanks

Seems like it works, are you not seeing this in some different environment?

Your example is slightly different, here's mine and the explanation of the real life use case.

My (planned) workflow of using d2 is to create multiple localised architecture diagrams from a single source reference architecture diagram:

1. Reference design - the first step of my workflow is to create a reference design diagram.
2. Localised design - the reference diagram is imported into multiple localised diagram documents.
3. Override of nodes in localised design document - details of the localised design are added to the nodes (names, serial numbers, etc).
4. Override of connections / exception handling in localised design document - as many of the reference designs are implemented with exceptions, I need to have the ability to remove previously defined connections in my localised design documents. However, as in my previous example, I don't seem to be able to remove an existing connection between nested nodes, or I am using an incorrect syntax.

I hope this explains.

Oh my bad.

You're right this is a bug. Setting connection to null works, but the method of targeting is too strict.

Will fix here shortly: #2318

Excellent, thank you for looking into this.

Will be fixed in next release
