Button sting
Posted: Tue Apr 19, 2016 1:15 pmThis bug stings like a wasp! - and took ages to pin down cos it causes continued crashing and reboots (cicciocb's gpio00 button to prevent autorunning has been worn out!).
To cut a long story short, I suspect there's a problem when trying to use more than 10 BUTTONs.
I've included the script I was working on (Alpha 13) which shows the problem in case it doesn't ring any bells, and there's an explanation of things embedded in the script.
I'm not looking for any problem get-arounds B.T.W. cos that's not the point of sending the script (and it's already been hacked to destruction from chasing down the pest anyway) - it's purely to demonstrate the problem.
I've pinned it down to being a >10 button problem by commenting out any one of the scripts earlier buttons, and then the original 'problem' button no longer causes a crash. And it is button specific, because commenting out a Textbox doesn't make any difference to the button crashing... but it's worth mentioning that if the cause IS because of using more than 10 buttons which aren't being handled properly, then perhaps the same >10 problem may exist for some of the other web components as well.
