Fix Comments in Joomla wrapper

The site is here: [login to view URL] You can login with test/test. I am having some issues with the comments section. There are three parts to this project, which are listed below. 1. After logging in go to browse at the top. Then double click on one of the items under "models". A details page will come up. If you try to leave a comment it will delete the details under "Model Details." This problem needs to be fixed. It should not delete anything. 2. I have a backup copy of the database. I need the old entries (the ones that were deleted) to be fixed. This will require some research to see which tables have the correct data. It cannot be a full database import, as that would overwrite new changes to the database. 3. After logging in go to browse at the top. Then double click on one of the items under "datasets". The comments here are not working. The "Add Comment" button does not do anything. This needs to be fixed so that when a user types their comment the comment appears under the box and is stored properly in the database.
