After upgrading to 16.2.0 we are having issues updating instances of Ideas attachment attribute.It is complaining about attachment attribute locked when it is not locked by any process. We are seeing this error message CMN-0015: Attribute 'my_attachment_attr_id' was locked and cannot be changed.
Steps to Reproduce:
1. Create attachment type attribute on idea object and api enable it.
2. Create a simple process to lock 1 or more attributes on the idea object but not the attachment attribute.
3. Run the process against given idea instance.
4. In MUX attempt to modify attachment attribute and notice error as CMN-0015: Attribute 'my_attachment_attr_id' was locked and cannot be changed.
Expected Results: It should allow to modify attachment attribute as it is not locked by a process.
Actual Results: It is throwing an error when attempting to modify an attachment attribute.
Resolved in 16.2.1 and 16.2.0.1. This was originally tracked as DE78793, and determined to be a duplicate of the problem noted in: DE78753.
