Using Nested DataLoader

[3jin-p]

@DgsData(parentType = "Type", field = "someFieldsA"
fun someFieldsA(dfe: ...) {
  val source = dfe.getSource<Type>()
  val loader = dfe.getDataLoader<String, SomeFieldA>(NAME)
  loader.load(source.id).thenApplyAsync {
  ... some converting code
 }
}

@DgsData(parentType = "Type", field = "someFieldsB"
fun someFieldsB(dfe: ...) {
  val source = dfe.getSource<Type>()
  val loader = dfe.getDataLoader<String, SomeFieldB>(NAME)
  // I want to use key from someFieldsA
  loader.load().thenApplyAsync {
  ... some converting code
 }
}

I want to use someFieldsA to someFieldBLoader's key
and each fields parent is same type
so i try to use nested dataLoader like under code

fun ..() {
 val loaderA = dfe.getDataLoader<String, SomeFieldA>(NAME)
 val loaderB = dfe.getDataLoader<String, SomeFieldB>(NAME)
 loaderA.load(source.id).thenApplyAsynce { someFieldA ->
     loaderB.load(someFieldA).load { ...}
 }
}

but it fall into an infinite waiting
how can i do?

When chaining data loaders, you need to make explicit call to dispatch. Documented here with example: https://github.com/graphql-java/java-dataloader#examples
