DPW & Project page: Edit button always edits last Party in list, irrespective of selection
In pages with party lists (CustomList displaying parties such as Owner, Contact etc), if the user hits
"edit", the dialog always shows the last entry in the list, irrespective of what is selected.
This is also a problem with the party list in Project page, but is not a problem with Citation page party
list, since there is no update from the DOM on this page - update is done by re-calling the
getPredicate() methods on all the party objects in the list.
