I have a question regarding the "autocomplete" function of controlled vocabularies in DSpace 7 during submission.
Intended behaviour: Autocomplete function after the input of some letters in dc.subject (such as in the Dspace 7 demo).

I added to local.cfg:
plugin.selfnamed.org.dspace.content.authority.ChoiceAuthority
= \
org.dspace.content.authority.DCInputAuthority, \
org.dspace.content.authority.DSpaceControlledVocabulary
and
choices.plugin.dc.subject = srsc
choices.presentation.dc.subject = suggest
vocabulary.plugin.srsc.hierarchy.store = true
vocabulary.plugin.srsc.hierarchy.suggest = true
vocabulary.plugin.srsc.delimiter = "::"
However,
during submission instead
of an autocomplete function another window opened when
I clicked into the field dc.subject:
In our DSpace
5.x instance autocomplete works well with presentation style
"suggest".
Am I doing something wrong or do others have the same issue?
