Step to reproduce:
- **Install liferay-ce-portal-7.2.1-ga2 Tomcat bundle
- Create a new Vocabulary in Global site and add two categories
- Create a new web content inside Liferay site and select category1 for it
- Create a second web content and select category2 for it
- Add Asset Publisher to some page and filter by category1
- Only one web content is shown in Asset Publisher
- Upgrade to 7.3
**Asset Publisher shows both web contents
Only web content with category1 is shown.
If new category is created after upgrade and it is used for filtering, then it works as expected. New category have treePath value set and those two categories that were created before upgrade have empty treePath in database.
