close/open event frames based on events, not transitions

I use analysis to toggle a boolean or integer from 0 to 1. This is used as source to close/open event frames (step continious mode). this is working fine in real-time. But when I do a recalculation for a part of time in the past (not until *) on t...

split analysis is real-time and recalculation part (different logic to be used)

It would be nice if we could have a "real-time" and "recalculate" part in an analysis. As source data could have changed you probably want sometimes the analysis to act in another way. Example: 2 attributes are used to trigger an event-triggered a...

Initial value for HasValueChanged

When an Expression or Event Frame Generation analysis evaluates for the first time, the function HasValueChanged returns True even if the value has not actually changed. More proper behavior would be to default to false. The same holds true when m...
