Zermelo created ISIS-3269: ----------------------------- Summary: Selecting the empty item from the choices of an optional parameter throws exception Key: ISIS-3269 URL: https://issues.apache.org/jira/browse/ISIS-3269 Project: Isis Issue Type: Bug Components: Isis Viewer Wicket Affects Versions: 2.0.0-M9 Reporter: Zermelo Attachments: SelectingNoneThrowsAnException.mov
In wicket viewer, selecting the empty (none) item from the select box (choices) of an optional action parameter throws an exception. I experience it both with Enum parameters and String parameters. To test it, you can add this snippet to SimpleObjects.java in SimpleApp. {code:java} public enum SomeOption {A, B, C} @Action public void a1(@Parameter(optionality = Optionality.OPTIONAL) SomeOption someOption) { } @Action public void a2(@Parameter(optionality = Optionality.OPTIONAL) String someOption) { } @MemberSupport public List<String> choices0A2() { return Arrays.asList("A", "B", "C"); } {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
