error with example

[vaibhavdaren]

The following example is running perfectly in firefox but it is not running in chrome https://turtle.sugarlabs.org/index.html?id=1528262976123644&run=True

It is showing in the console log:-

[vaibhavdaren]

FireFox Version: 60.0.2 (64-bit) Chrome Version: 67.0.3396.79 (Official Build) (64-bit)

[walterbender]

Runs fine in chromium 66. Can you please attach the entire console log (please select-all and paste it here rather than attaching a screen shot)? I think the error might be due to something happening earlier.

I think I see what is going on. It seems to be related to the auto launch of the status matrix.

[vaibhavdaren]

Yes the execution of the program begins with start block but somewhere in between the status matrix is launched which stops the running code in turtle blocks and shows the error "Cannot read property 'init' of null" in the console log when we run again. To correct this, I think we have to make the order of execution such that first the status block part of the code executes before the start block part of code.

[walterbender]

Could you please test again? I made sure that the widget is created before trying to initialize it.

[vaibhavdaren]

sometimes it runs fine, occasionally it is giving an error. I am not able to figure out exactly why.

[walterbender]

Can you please post the console.log file for when it doesn't work?

[vaibhavdaren]

[1] when the project is working Working.log [2]when the project is not working NotWorking.log "these are the complete log"

[walterbender]

What version of Turtle are you using? (I ask because the line numbers reported in the console output don't match any version I have and it seems that they are from a version that does not have my patch to fix this bug).

I cannot reproduce this bug on Chromium (67.0.3396.79). What version of Chrome are you using? I assume you are using turtle.sugarlabs.org?
