Claus Ibsen commented on FORGE-2526:
------------------------------------

Yes getSelectedIndex is what I need.

Maybe on the change listener, you can have getSelectedIndex as well, eg you have ValueChangedEvent
https://github.com/fabric8io/fabric8/blob/master/forge/addons/camel/src/main/java/io/fabric8/forge/camel/commands/project/CamelAddEndpointCommand.java#L106

Maybe it should be getNewSelectedIndex an getOldSelectedIndex for the ValueChangedEvent.

> When using the UISelectOne then you cannot today know which index the user selected, whether it was the first, the last, or some other in between.
> You can only get the value, and then from the value you need to determine yourself if it was the first, last etc.
> Also due to bug FORGE-552 the returned value can be invalid, and you would not have a way of know exactly what was selected.
> To be able to get the index would be great. This is also what other UI frameworks offers in both Java and Javascript etc.
> The same thing would be nice on the change listener, where its applicable.
