Hi,
I have a general question regarding modules.
How are the module classes loaded and what is the lifetime of such a class?
Is it either

a singleton which depends on Eclipse runtime
existing during a script runtime, if module is loaded till end of the script
instantiated at every call of a method
another option?

Regards
Daniel

It is option 2. The script runtime will create an instance on the first loadModule() for a dedicated module. A subsequent call to load the same module will recycle the previously loaded instance, not re-initializing it. So if a module has members they will not get resetted on a second loadModule.
However the script wrappers to call exposed methods get refreshed on a subsequent loadModule. You might want to look at this by debugging a JS file and enable debugging of dynamic code fragments. it allows you to step into loadModule() to see what happens in the background.
