If you're running tests, and your tests are 'normal' unit tests (so no integration) than my guess is that they are not there. Have you tried the console? Hi Puran,

Like I described, it’s an implicit variable in the console. If you’re running tests, and your tests are ‘normal’ unit tests (so no integration) than my guess is that they are not there.

Have you tried the console?

Inner implementation of this plugin will actually create two tables. Tag table Tagging table with important columns tagId, taggableType (actually class name of tagged domain object). I prefer this approach because I don't need tag field in my domain classes but I can tag them. Another advantage is that querying tag cloud from the database is easier at least from my point of view. Tagging.executeQuery("select distinct t.tag.name, count(t.tag.id) from Tagging t where t.taggableType=? group by t.tag.id" Jan For grailstutorials.com I used ‘act as taggable’ plugin.
