JavaScript build_race_courses.js crashes opencpn

[LordLaingholm]

Hi all,

I've recently installed the JavaScript plugin and loaded the build_race_courses.js script however when I run the script OpenCPN crashes immediately. I tailed the opencpn.log file at the time but no data was added to it. The JS console remains open. I've repeated the same exercise several times with the same result. Other javascripts run fine.

I'm running OpenCPN 5.8.4-1 on Linux openplotter 5.15.76-v8+, Raspberry Pi 4, I'm using VNC to access the pi.
pi@openplotter:~ $ cat /etc/os-release

I'm new to javascript and the js plugin however I wrote a couple of scripts that worked fine.

i've done a bit of debugging and if I comment out the second line in this dialogue ({type:"text", value:"Enter a pattern...) opencpn doesn't crash. however nothing happens at all. I'm expecting a couple of diaglogue boxes to open, correct? I focused on this line as I thought it might have an extra ''.

config = [
{type:"caption", value:"Race route creator configuration"},
{type:"text", value:"Enter a pattern for the waypoints to be included in the racemark list\nThis can be a regular expression.
\nThe example matches all waypoints with names starting with 'Start', 'Finish' and RM\n(Leave blank to include all waypoints)"},

Any thoughts or pointers on how to best debug this appeciated.
thanks

I moved this to be an issue but you seem to have managed to reply to it as the original discussion. So we have our wires crossed. Please see here.
