Hi Wilker, I have been going the same way and never really found out why this happens (I am using http-kit instead of jetty). However, one thing that I did not knew was that a refresh will delete references of vars. So if you keep your stop function somewhere and call refresh before the stop function you will not be able to stop jetty anymore and hence, when you try to start it, it is already running.
I implemented my own component library, having the same problems, especially when I was using a lot of protocols / records (may have been just a coincidence) and finally found about the hara.component library. I am using this one now and seem to have less problems. But, to be honest, I cannot believe that stuarts component library is the problem, but my way of using it or coding. Of course I'd be interested too to hear other opinions. Best Regards, Sven Am Sonntag, 14.
