Red 'error' rectangle instead of scatter chart

[Anne van der Bom]

I am using the visualization toolkit from a GWT application using the
visualization api version 1.1.2-rc. It has been working flawlessly for
months. Until this morning.

When I restarted my application this morning, instead of my
ScatterChart a little red rectangle with the text 'error' appeared.
That's all, just 'error', no details. Since I did not deploy a new
version, I must conclude that it has something to do with the new 17
august release. Without an option to switch back to the old version, I
could do nothing but try and find the cause of the error.

After tinkering around a bit, I managed to discover the cause of the
error. But Google did absolutely nothing to put me on the right track.
A little red rectangle with the word 'error' and absolutely NOTHING in
any log file or DevMode console or wherever I could think to look. It
is like being dumped in the middle of the Amazon with a rusty compass
and flashlight without batteries.

Second thing I would like to get off my chest is that it is
unacceptable that you simply dump a new version upon us without choice
or option to keep on using the old version. If undermining the loyalty
of your users is the goal, then this is definitely the way forward.

After this experience I know I can not recommend the Visualization
Toolkit to a client, since no company that I know of would accept this
sword of Damocles hanging over their heads.
