[iRail] bug in generated jsonp string for liveboards?

Tue Jan 10 15:07:31 UTC 2012

Hi Christophe,

It even seems worse than that. If you look at my tests at
http://users.skynet.be/bert.simon/getThere/getThere.html#gentbrugge/terhulpe
n, and you click on one of the connections, I seem to have  a failure almost
every time (meaning 1 in 3 trains for this case) (see console). It is either
this one, or the error about a bad JSON string (issue 22)...

How did you work around the problem? Retry after one minute? 

Regards,
Bert.

This happens more often than you think ;-) When working on my app, I was
always wondering why it took so many time to get nothing... I happens 5-10%
of the time, but seems better today.
