The title alone would probably result in a chanting "NO!" as a popular answer, but please let me elaborate.
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.
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.
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?
