steps to reproduce:
1. add an Asset Publisher portlet to a page
2. create two web content assets and give them different tags e.g. tag one "web" and the other "content"
3. navigate to one of the tags via the url by entering this http://localhost:8080/web/guest/home/tags/[tag you created]

expected behavior: the AssetPublisher will display its entries based on the tag you enter
actual behavior: no filter is applied and the AssetPublisher shows both web contents.
