endless recursion with "select" in Timeline chart

[Chuck Tung]

I needed to create a timeline chart, where I can click on a row and open a URL.  

Once a row is selected, however, if you click the same row again, the selectHandler does not fire (I assume because there is no change to the selection?)

I was trying to work around this by clearing the selection as part of the selectHandler.  This works for many other charts but does not work for the Timeline chart.

https://jsfiddle.net/rg388awv/

I took the timeline chart example from the google docs, and added:

         function selectHandler() {

            chart.setSelection([]);

         }

        google.visualization.events.addListener(chart,'select',selectHandler)

It fails to clear the selection, and I get "maximum call stack size exceeded" errors on mouseover

Any ideas?

Seems the problem is related to setSelection([])

This alternate approach has the same problem:

        function mouseOut(e) { chart.setSelection([]); }

        google.visualization.events.addListener(chart,'onmouseout', mouseOut);

Hi Chuck,

Interesting problem you have found.  Thanks for reporting it.  We should be able to allow the setSelection in the selection handler but I don't know how difficult it will be to fix.
