Hello all,

In own of my test-javascripts I'm using the line:

const engine = Engine.getEngine(); // get first registered engine

Engine is a custom class (JSClass) that I've build.

When I run this script for the first time all seems to be okay.

When I run the same script for the second time I get an error that a const
variable is redefined.

Here's the code that runs the script (C++ wrapper around Spidermonkey)
void Context::runScriptFile(const char* source)
{
jsval result;

JSScript* script = JS_CompileFile(context, globalObj, source);
if (script)
   {
  JSBool ok = JS_ExecuteScript(context, globalObj, script, &result);
  if (ok == JS_FALSE)
     {
     _STD::cout << "error in Context::runScriptFile()" << _STD::endl;
     }
  JS_DestroyScript(context, script);
  }
}

The context is not destroyed. How can I prevent this error?

I'm not quit sure if I've handled the context right. When I create the
JS_Runtime, I also create 1 JS_Context. This context is destroyed when the
JS_Runtime is destroyed.

With kind regards,
Peter Paulus
