The eZ Recommendation extension (Yoochoose) causes a JS error that seems to be related to jQuery not being defined correctly: "Uncaught TypeError: undefined is not a function".

We've tried this with a fresh eZ Publish 4.7 installation. As soon as the recommendation extension is activated the error will show up (the system works fine before activation).

Steps to reproduce:*

• Install eZ Publish 4.7 Enterprise edition
• Load one of the public (non-admin) pages. Verify that no JS errors are reported.
• Install and activate the eZ Recommendation extension (v.1.1)
• Load one of the public pages. There will now be a JS error.
