I'm trying to apply a set of tags to a single contact using API3 but I'm getting an exception during the sequence of API calls.

The flow (which I refer to later as "test_ng") is:

loop (n=0..N) {
  tag_id = Tag-Create(tag_name[n]) //create a tag
  EntityTag-Create(tag_id) //assign the tag to a contact
}

What I found is that the first time through the loop all works well -- a tag is created and applied to a contact. But the second and all subsequent times through the loop on the EntityTag-Create call I get:

Caught exception: 'XXX' is not a valid option for field tag_id

where XXX is the tag_id.

I can see then that tag_name[0] and tag_name[1] are indeed created, but tag_name[1] does not get assigned to the contact.

Now here's the fun part. If I instead run the following (I'll call this test_ok):

loop (n=0..N) {
  tag_id[n] = Tag-Create(tag_name[n]) //create all the tags
}
loop (n=0..N) {
  EntityTag-Create(tag_id[n]) //assign all the tags
}

then everything works as expected.

And If I run

  test_ok();
  test_ng();

then test_ok passes and test_ng creates the exception during each iteration of its loop.

And If I run

  test_ng();
  test_ok();

then test_ng creates an exception on all but its first iteration and test_ok creates the exception on each iteration.

So it appears that the API becomes unhappy performing the sequence:

  EntityTag-Create
  Tag-Create
  EntityTag-Create //Exception!

and this makes all subsequent calls to EntityTag-Create cause an exception, apparently for the lifetime of the process.

I've attached a test script which demonstrates the problem. It produces the results shown below.

Problem was observed on CiviCRM 4.5.3 and 4.6.beta1.

I believe this is a bug. Any thoughts?
