TIMELINE. Timeline Load Error in IE #151

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
My site is http://calliesadventures.com/Multimedia/Snippets.html.

I have a three band timeline (month, year and decade) which works fine in
safari and firefox (both mac and windows); however, I get two caught
exception: [object Error] when the year and decade bands are loaded with
the events. The month band loads fine. When I comment out eventSource out
of the year and decade band, no error.

Windows XP, IE 6.0 and 7

Could you please paste in here the javascript code you use to construct the
Timeline?

I have traced the problem down to the showEventText attribute. If I
eliminate it from the bottom two time bands, the error goes away. This
seems to be the problem if you have more than two bands. I just created a
second theme and set the event label length to zero. It solved my problem.
