RE: [BUG] : java.util.EmptyStackException on EnvironmentStack

[Amir Rosen <am...@cti2.com>]

Hi,

I added a patch in my servlet extending the cocoon servlet, detailed below.

Is this going to solve this bug ?


public class SensesServlet extends CocoonServlet {
...
	public void service(ServletRequest request, ServletResponse response)
			throws ServletException, IOException {
		EnvironmentStack es = CocoonComponentManager.getCurrentEnvironmentStack();
		if (es != null) {
			es.clear();
			es.resetOffset(0);
		}
		super.service(request, response);
	}

Thanks,

Amir Rosen
