[GitHub] [netbeans-html4j] jtulach opened a new pull request #44: WIP: Support asynchronous calls from JavaScript into Java
jtulach opened a new pull request #44:
URL: https://github.com/apache/netbeans-html4j/pull/44
Adding
```java
@interface JavaScriptBody {
boolean wait4java() default true;
}
```
When set to `false` then each call into Java (via `@pkg.Clazz.method` syntax) returns (ideally real JavaScript) `Promise` with `then` method.

Review comment:
The whole `ko4j` bindings are now ready for `wait4java=false`, however, that means various updates may happen asynchronously. To get ready for that I had to modify the _Test Compatibility Kit_ to work in _quantums_: https://github.com/apache/netbeans-html4j/commit/1e398f86e740ba4aebef9457e0bea2dadf651b56
