When i invoke a POST to an XPages with a RestService Control, the renderService Method is executed twice when the RESTService is called the FIRST time (after clean of the project).

XPages:

<xe:restService id="restService2" pathInfo="community"
    ignoreRequestParams="false" state="true" preventDojoStore="true">
    <xe:this.service>
        <xe:customRestService contentType="application/json"
            serviceBean="ch.belsoft.rest.RESTServiceBean">
        </xe:customRestService>
    </xe:this.service>
</xe:restService> 

Java Backend with the renderService Method:

@Override
public void renderService(CustomService service, RestServiceEngine engine)
        throws ServiceException {
    try {
        System.out.println("inside RESTServiceBean.renderService:"+System.currentTimeMillis());
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

When i make a Clean of the project and call the REST Service, it prints 2 times the milliseconds..

How can i prevent that? got the latest ExtLib 901v00_16.20160128-1014
