Duplicate in copyField

[Jonatan Fournier]

Hi,

I have something strange happening (4.0-BETA), I have a title field:

<field name="title" type="string" indexed="false" stored="true"
omitNorms="true"/>

And a copyField:

<copyField source="foo" dest="title"/>

Note that I don't have multivalue set for the title field, but I do
end up with multiple value in my field:

{
  "responseHeader":{
    "status":0,
    "QTime":371,
    "params":{
      "indent":"true",
      "wt":"json",
      "q":"domain:dyslexia-test.com"}},
  "response":{"numFound":1,"start":0,"maxScore":13.414578,"docs":[
      {
        "id":"9f13185f8134ff75cb1c6106ac5db63f",
        "foo":"bar",
        "title":["bar",
          "bar"],
...
}

I made two operations on that document.

First I created it by populating some of its fields, and in a second
pass, I queried the document via "id" add other values to the
un-populated fields and send the document back.

Why is there more than one value for title? At worst should the 2nd
operation overwrites the original value?

Cheers,
