What are these pid things described in the Web Client API under mx.ui, for example var pid = mx.ui.showProgress(); // show progress dialog mx.ui.hideProgress(pid); // hide it again Is that pid something you have to manually handle or can you actually get a list of the running microflows, kinda like a process list, in Mendix? If so, how can I retrieve all the pid to try make something like those ps or top commands in Unix and Linux? Thankyou
