I would like to understand better how system.util.invokeAsynchronous works.

Does system.util.invokeAsynchronous use a thread pool? If so, how many threads does the pool use?

Does system.util.invokeAsynchronous create and run SwingWorker tasks?

I am using Ignition 7.7.

Thanks,

It doesn’t use a ThreadPool, it just creates a new Thread and Runnable for invocation.
