addField - possible error?

I have the following problem.

I have big form (approx. 20 items) with ImageUploader. All form items are uploaded with iu.addParam("AdditionalFormName", "addDocument");. But some form items which are added or removed dynamically must be explicitly added with AddField() method. Here is not problem but when I then remove all dynamically added form items (without page refresh) and I upload file again then there are values from addField even when form items doesn't exist yet. It works fine only when I call removeField().

Once again with steps:

1) add dynamically form items (text fields)

2) upload files with form items

3) remove dynamically added form items

4) upload files again => component sent removed form items

It seems as component saves values for addField items and sends them even when there no these items in the form yet.

I think this is bug but I would like to know your opinion.

Thank you, PETER.
