Hi onsir,
Any reason why you are not using
<window .... use="${priceController}">Well, if you are using fully qualified class name as the value for use attribute then ZK will instantiate a new instance of that class and Spring framework will have no chance to do any injection of services into the instance as it isn't instantiated and maintained under Spring's control. If you still want to use fully qualified class name instead of EL expression then you need to get the required spring bean yourself with SpringUtil#getbean(String) (refer javadocs )
