JSON-type component breaks

Question

Hello!

The following examples break, though should not:

1.

@startuml
json someJson [
1, 2, 3
]
@enduml

2.

@startuml
json "some json" {
"a": 1
}
@enduml

Hello B., and all,

See similar reported issue here:

• https://forum.plantuml.net/16464/%25load_json-not-working-where-root-is-array?show=16465#c16465
• https://forum.plantuml.net/16408/is-it-possible-to-include-json-as-an-external-source?show=16434#c16434

For your second cases, could you add an alias, as:

@startuml
json "some json" as J {
"a": 1
}
@enduml

For the first case, @PlantUML team, see also this example:

@startuml
json someJson {
[1, 2, 3]
}
@enduml

If that can help, for debugging...
Regards.
Th.

UPDATE: filed a bug on this in: https://forum.plantuml.net/16640/some-arrows-from-json-component-to-another-component-fail

The-Lu, thank you!

This worked. However, run into the following issue:

@startuml

json "some json" as a {
 "a": 1
}

component b {
}

a ->> b

@enduml

this will work if you replace the arrow from ->> to ->

However, should work with all arrow tips

Hello B.,

Thanks for the report,

FYI that is now fixed and implemented on v1.2024.8:

• Release v1.2024.8 · plantuml/plantuml (github.com)

- Thanks PlantUML team for your work.

For 1./

Here is the current working example:

@startuml
json someJson [1, 2, 3]
@enduml

Or

@startuml
json someJson {
  [1, 2, 3]
}
@enduml

See:

• feat: feat: allow all JSON Values on JSON Entity by arnaudroques · Pull Request #1970 · plantuml/plantuml (github.com)

For 2./

That is now fixed.

@startuml
json "some json" {
"a": 1
}
@enduml
