String component not working #1239
Description
For a simple StringInput component like this:
@Component
public class SimpleComponents {
private final Terminal terminal;
public SimpleComponents(Terminal terminal) {
this.terminal = terminal;
}
@Command(name = "string")
public String string() {
StringInput stringInput = new StringInput(terminal, "Simple string", "<default>");
StringInputContext stringInputContext = stringInput.run(StringInputContext.empty());
return "Value: " + stringInputContext.getResultValue();
}
}I get the following exception when running the command:
