There is an error in asset publisher portlet. Steps to reproduce error :
1) create some web contents using control panel- web content.
2) assign some tags from web content-categorization option for each web content.
3) add asset publisher portlet and tag navigation portlet in a page and use as default.
Now, when we click on a tag, all the related contents a showing up. If there is no content assigned for a particular tag(need to check the option from configuration of tag navigation portlet), "No result message" will come up inside asset publisher portlet. every thing goes well. The problem is when i manually change the tag name(which does not exist) in the url , all the created contents are showing up. Expected result is "No result message" should come up inside asset publisher portlet.
