Concat PDF files not working and unable to flatten image field.

Hello,

On Oct 13, 2010 I entered a case "concatinating xfa forms is not allowed" and I finally received notice on June 5, 2014 that the issue was resolved. I was able to download the latest version and test and so far it appears that I can add pages from one PDF document to another, but the actual Concatenate method while passing in the path to two PDF files is not working. I believe the add pages option will work for our needs, but I would like to understand why such a simple process of Concatenate is not working.

Also, another issue I am having with this new version is trying to fill in the form fields and flattening the fields. Flattening a textbox seems to work fine, but I receive the message "Some fields are malformed, and may not work as expected. Please contact the author for a fix" when I try to flatten an image field. We are using the barcode assembly to create a barcode as a stream then using that stream to populate the image field.

I have a sample vb.net app that is showing the problems I am having.

Thanks!
