Redmine

Hi every body. Problem: see subject.

I was using redmine 1.2.1 until now. There the problem apears also. I was intrested if it still remains in the new redmine version. And it seems to be. I found many other questions to this problem. But no resolving answer. Maybe it is because searching for 'moving issue to new project via api in redmine' (or any thing else issue related search term) throws a infinit amount of results.

I use:
ruby: ruby 1.9.3p392
postgres: 9.1
gems:

• actionmailer (3.2.12)
• actionpack (3.2.12)

Redmine info page shows this:
Environment:

Redmine version 2.2.3.stable
Ruby version 1.9.3 (x86_64-linux)
Rails version 3.2.12
Environment development
Database adapter PostgreSQL

Description of what I do:
PUT /issues/8688.json?
with {"issue":{"project_id":"59","assigned_to_id":"7","notes":"BlaBla!"}}

Description of what I expect:
The issue 8688 is assigned to user id 7 edited in notes with blabla and the new project id is 59.

Works great for assigned to and notes. But not/never for project id. This also down in version 1.2.1. I try this because the redmine rest api documentation offers this. But also I'am very intrested in this because of automatic ticket moving. So every help is appreciated.

Thanks a lot!
