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}
