I just had a look at the method in P10.�� And one line of code is added to the emptyList method.�� I copied it to p9 and it no longer throws the exception.�� I will continue to look to see if there are further differences I need to ���back-port��� ( or perhaps I just need to download the latest version of Spec2.

Ah.  OK. Thanks.  Unfortunately I am working on a P9 image.  I will have to go through the chore of transferring my work to P10 I guess.

I had this same issue and reported in v9. It appears to be fixed in v10 and from what I understand there will be no ���back-port���.

I think this might be a bug.

 

When I send emptyList to a non-empty SpDropListPresenter it reports ���SubscriptOutOfBounds: 1���.

 

I seems to be due to emptyList setting the list model to a new empty OrderedCollection and a later method trying to access the first item in the collection.

 

Attached screen shot shows the debugger window.

 

If it is a bug please report it and if possible advise a workaround.

 

If not a bug please advise the correct way to clear  or change the contents of a drop list.

 

Many thanks

Robert
