Tooltips not working in the main table

[oscargus]

There is supposed to be a tooltip for the red incomplete entry field, from IncompleteRenderer.java:

        setToolTipText(Localization.lang("This entry is incomplete"));

However, this is not working on either my Windows 10 laptop nor my office CentOS machine. Anyone have it working or have an idea what is wrong?

I tried the slightly different approach in http://stackoverflow.com/questions/9467093/how-to-add-a-tooltip-to-a-cell-in-a-jtable as well (applied it in GeneralRender) but that didn't work either.

Tooltips are working only for cells, where the content is exceeding the columns width.

I'm not sure (although I wish that was the explanation): http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#celltooltip
