Comment # 5 on bug 943870 from Michael Andres

@Huha: In libzypp-15.15.0 I changed ui::Selectable::pickStatus, so it can be
used with non-multiversion PoolItems as well:

PickStatus install requests for non-multiversion PoolItems are translated into
'setCandiadate/setStatus' (clearing any other PoolItems install request).

PickStatus install requests for multiversion PoolItems will additionally clear
any pending non-multiversion install request.

This might help you fixing the UI code.
