Autobinding does not work for spring bean alias

1. I created Grails 1.0-rc4 application.
2. I created the following controller:

   class HelloController {
       def str1
       def str2
       def exampleService
   
       def index = { 
         def serviceResult = exampleService.serviceMethod()
         render "hello $str1 and $str2. $serviceResult"
       }
   }
   

3. I created the following service:

   class ExampleService {
       def str1
       def str2
   
       boolean transactional = true
   
       def serviceMethod() {
   
   	  "$str1 and $str2"
   
       }
   }
   

4. I updated resources.xml:

   <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="
   http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
   	
     <bean id="str1" class="java.lang.String"/>
   
     <alias alias="str2" name="str1"/>
   
   </beans>
   

5. Then I went to http://localhost:8080/myapp/hello and see "hello and null. and null".

It seems that autobinding does not work with spring aliases both in Controllers and Services.
