Hello all,
To continue, with the Kirchsth's answer...
Here are some workarounds:
With nested link, using Unicode null:
@startuml
queue "<U+0000>" as noname {
component withname
}
component "Component A" as A
A -> withname
@enduml
Without nested link, using sub-diagram:
@startuml
queue q [
{{
component withname
}}
]
component "Component A" as A
A -> q
@enduml
If that can help,
Regards,
Th.
