Pasting doesn't handle duplicates

[alexsmelyakov]

Pasting a list with duplicate items leads to "Duplicates in a repeater are not allowed" error.
The tiUtils.findInObjectArray method is given empty array to look through for every item.

Example:

Sample data "aaa, bbb, ccc, aaa"

I'm using this hack as a (total) workaround, for lack of time to implement a proper fix,
fortunately the ng-paste gets called after the paste
so I can clear the temp array

on-tag-adding="validateNotDup($tag)"
ng-paste="afterPaste()"

        var tmp_add = []

        scope.validateNotDup = function(tag) {


          var alreadyAdded = _.find(scope.myTags, function(t) {
            return t.text == tag.text
          })

          if(alreadyAdded) {
            return false
          }


          alreadyAdded = _.find(tmp_add, function(t) {
            return t.text == tag.text
          })

          if(!alreadyAdded)
            tmp_add.push(tag)

          return ! alreadyAdded
        }

        scope.afterPaste = function() {
          tmp_add = []
        }

Just wanted to add that I have recently used this work-around (which was a life-saver) but I also noticed that it has a minor bug. If you use max's code above, you will also need to add another hook:
on-tag-added="onAdd()"

scope.onAdd = function() {
  if (tmp_add.length == 1){
    tmp_add = [];
  }
};

The reason for this is that the on-tag-adding hook is called regardless of whether the input was manually added, or added on paste. Therefore, if a tag is added manually, it's value is added to tmp_add indefinitely, because the after-paste function is not called to clean up tmp_add. This means that if that tag is deleted, the user will be unable to add it back because its value is in tmp_add. While a paste would flush tmp_add, that's not intuitive or practical. I found that while on-tag-added is called for each tag, it happens after each on-tag-adding is called, but before afterPaste. Since a paste always clears tmp_add thanks to ng-paste, and a manual entry can only add one tag at a time - if the length of tmp_add on-tag-added is 1, then we know that there was either a manual entry or a single entry paste - either of which could not result in a duplication error. Therefore, clearing tmp_add is safe and prevents the persistence of manual tags!

Hopefully this will help the next person who finds this page!

(Note: Alternatively, you can drop the ng-paste hook and use the following)
on-tag-added="onAdd()"

scope.onAdd = function() {
  if (tmp_add.length > 0){
    tmp_add = [];
  }
};
