Hello to everyone,
I have an issue inside one of my projects. I have a project library script “TrkPanels_Dev” which has a method called "Update”. This is called by a client timer event every two seconds.
Whenever I change the TrkPanels_Dev.Update method and save, in order to update it on the running client instance, I need to logout or to close the instance. It seems a little strange to do all this work in order to change the library script at runtime.
I start to notice that inside the gateway, this message appears:
