Minor Could not make a drop down list using list of Strings type in Configuration class as it is described in tutorial (https://talend.github.io/component-runtime/main/0.0.7/gallery.html):
@Option
List<String> config;
But seems like it works with enum, for example:
public enum OutputAction { INSERT, UPDATE, UPSERT, DELETE } @Option @Documentation("TODO fill the documentation for this parameter") private OutputAction outputAction;
