Line styling not recognized when using ELK

[StephanPirnbaum]

I'm using C4-PlantUML with ELK, as it regularly produces better outputs.
However, I ran into an issue when using e.g. lineColor or lineStyle.

In the following example, the relation defined using standard PlantUML syntax is correctly rendered, whereas using the C4-PlantUML it is not.

@startuml
!include <C4/C4_Component>
!pragma layout elk

AddRelTag("DEF", $legendText="Java-Abhängigkeit", $lineColor = "#blue", $lineStyle = DottedLine())

Component(A, "A")

Component(B, "B")

A -[#orange,dashed]-> B

Rel(A, B, "Test", $tags="DEF")
@enduml

This leads me to the conclusion that ELK itself has no issues with styling lines (which would have had me wonder, tbh).

When not using ELK, the example is working, however.

@startuml
!include <C4/C4_Component>

AddRelTag("DEF", $legendText="Java-Abhängigkeit", $lineColor = "#blue", $lineStyle = DottedLine())

Component(A, "A")

Component(B, "B")

A -[#orange,dashed]-> B

Rel(A, B, "Test", $tags="DEF")
@enduml

For me, that looks like an issue of the combination C4-PlantUML syntax and ELK.

Hi @StephanPirnbaum,

thank you for the finding, but I think your conclusion is wrong. I think it is elk related, I can reproduce the problem without C4 too. Samples see below.

I entered a bug in the PlantUML forum

Hi @kirchsth

thank you for the fast investigation and reply. You're right, I was not considering using skinparam which would explain the difference to my example. I can confirm your conclusion.
