Hmm, I use that technique a lot myself. Definitely needs fixing. Please
raise a ticket.
~~~
In the meantime, a workaround that should work (we have the equivalent in
Estatio) is:
public static enum Category {
Professional, Domestic, Other;
@Programmatic
public Integer myIndex() {
if(this == Professional) { return 1; }
if(this == Domestic) { return 2; }
if(this == Other) { return 3; }
}
}
Another workaround that *might* work is to annotate with @ObjectType:
@ObjectType("TODOCATEGORY")
public static enum Category {
/// your implementation...
@Programmatic
public abstract Integer myIndex();
}
Thx
