On people picker column where is allowed multiple entries, I should restrict entry to only one user in edit form.
To explain why I need this.
Users can enter multiple values to people picker column in new form, after saving item SPD workflow creates as many new items as there were users in people picker column and deletes original item. So in newly created items there is only one user in people picker column.
What I now need is to restrict users to enter additional users in edit form.
I found that there is SPServices function SPFindPeoplePicker, here but not sure how to pull pull number of entries from dictionaryEntries.
Another thing that came up my mind is to check in workflow if there is on item edit on people picker column more than one user and if yes to leave only first entry.
Other than these, I found nothing. Do you have any idea and suggestion how could this be achieved maybe easier?
