addModelChangedListener is working fine in personal engine (Local server) but not work in my testing server. Its not triggering. How to trigger in all the environment ?
What is the solution of this ?
That doesn’t make sense to me. JavaScript is the same in each browser, independent of the server. There may be some differences due to security, such as CORS. You will need to debug the circumstances for the different behavior. Something must have loaded differently – maybe different versions of some files?
