WebParsers only work on first load, not refresh - multiple connected

[poisonborz]

I built 3 connected queries for a weather widget. IP Location, city -> Weather.com code for city -> Weather.com query.
The problem is that this setup works only on the first load. Eg. when I right click/refresh there is no value, and I can't debug where it gets stuck. I sometimes managed to consistently crash Rainmeter with this.
Is there some error? Is there a better pattern for this setup?

Code: Select all

[MeasureLocation]
Measure=Plugin

Instead of setting an UpdateRate=-1 option on parent WebParser measures ([WeatherCode], [MeasureWeatherNow] and [MeasureWeatherForecast]) better disable them adding a Disabled=1 option to each of them, then enable and update each of them when the previous measure gets the values.
So:

• Add a Disabled=1 option to [WeatherCode], [MeasureWeatherNow] and [MeasureWeatherForecast] measures.
• Remove all UpdateRate=-1 options.
• Add the following FinishAction options to the appropriate measures:

  Code: Select all

  [MeasureLocation]
  ...
  FinishAction=[!EnableMeasure "WeatherCode"][!CommandMeasure "WeatherCode" "Update"]
  ...
  
  [WeatherCode]
  ...
  FinishAction=[!EnableMeasure "MeasureWeatherNow"][!EnableMeasure "MeasureWeatherForecast"][!CommandMeasure MeasureWeatherNow "Update"][!CommandMeasure MeasureWeatherForecast "Update"]
  ...

  Take care to not remove the existing options, just replace / add the above ones.

Yeah, it now works also on forced refreshes - and is also more efficient! Thanks a lot for looking through the code!
(As for Rainmeter, it's still a bit unsettling that it crashes when 2-3 webparsers start at the same time)

Not exactly the same question, but there is a known issue of WebParser measures: https://forum.rainmeter.net/viewtopic.php?f=5&t=26117&p=136507&hilit=webparser+hang#p136507
I'm glad if you got it working better.
