I just want to disable all hover text for the column heading. However with the code below a nuisance hover text of the column title appears when the mouse is over the column heading.
The datasource for the grid is built by cursoring a datasource from another API and building the local data source on the fly, in case that offers a clue...
The results are shown in the attached png
title: "Source BOGUS", // causes the hover problem
style: "display: none"
template: '<img src="images/zoom.png" width="16" height="16"/>'
