Hello.

Thanks for your response. I created a sample and posted its three files onto Pastebin. Be sure to name the files accordingly on your local file system.

teste09.html

teste09.js

When you open the sample page and use TAB to move focus to the grid component, you will notice that the grid description is not spoken by JAWS. Instead, only the value associated with the grid's current cell (as given by the /aria-activedescendant/ attribute) gets read.

You can try commenting out the fifth line in teste09.js (shown below) to get the grid's description to be read.

updateGrid(grid, function() {});

I have actually managed to get my desired outcome by using a time-out but I see this as a fragile sort of kludge. Replace the javascript line above with the following to hear what the expected results are:

setTimeout(function() { updateGrid(grid, function() {}); }, 3000);

Thank you for your time.

Regards,
