The title alone would probably result in a chanting "NO!" as a popular answer, but please let me elaborate.
Background
We have a table of Something:s. Each Something can hold 1-5 Items. In the table there's a column which displays how many Items each Something has. This column consists of a cell for each row containing a link-styled label saying 1, 2, 3... depending on how many Items it has. If the user hovers the cell, a tooltip will appear displaying a text with the Id:s of the Items contained in this Something.
Problem
However, the label (which I have made look like a link) is not clickable (of course the user may click, but nothing will happen). The reason for making it look like a link is to attract the user to it, making the label communicate that "Hey, I have something here". The user will hover it, perhaps try and click it, and the tooltip will appear.
I'm not really sure how else to communicate the affordace for a tooltip.
Question
So my question is if this would be considered ok UX? You could argue that I'm fooling the user but is the gain enough to justify that?
Own opinions are OK but I would love some factual evidence strengthening your case.
EDIT : I guess a side question here is if it's ok to have a tooltip for something that isn't a tool but a display of data?




titleattributes notalt:). Only old versions of IE (inappropriately) displayaltas a tooltip, it's meant for accessability – Ben Brocka♦ Apr 18 '12 at 18:39
