Hey @Rox,
Thank you for reaching out to us. You really should have a look at the migration guide, as these topics are covered there. We cannot debug every compiler error here for you, nevertheless here are the answers to your three problems:
// 1 - That should fix it as the signature is now:
// GeData( const CustomDataType & data, Int32 type )
t_data = GeData(bbs, CUSTOMDATATYPE_BITMAPBUTTON);
// 2 - Selections are now COW and make a distinction between being mutable and immutable.
const BaseSelect* const mySelection = sTag->GetBaseSelect(); // immutable
BaseSelect* const mySelection = sTag->GetWritableBaseSelect(); // mutable
// 3 - Same story here, GetCustomDataType returns immutable data now, the method is also templated
// now, so you do not need to cast things anymore.
const InExcludeData* const myList= bc->GetCustomDataType<InExcludeData>(MY_ID);
InExcludeData* const myList= bc->GetCustomDataTypeWritableObsolete<InExcludeData>(MY_ID);
Cheers,
Ferdinand
edit: forgot the template argument in BaseContainer::GetCustomDataType
