Hi Vladimir,
I have the same problems from time to time…
Do you remember on what you where working on when it crached and config.js got empty?
I have 3 things in mind and watching their behavior untill I have a curtain result to report.
appconnect:
- Datastore component
- Datav View component
serverconnect:
ArrayList
Where you modifying any of those while it happened? (bind values, set parameters etc…)
