<on-start> service not called

[canal]

Hi,
everying works except that the <on-start> service is not called...googled but seems that nobody had similar problem so far.
What I am using:
Spring 2.5.6, Web Flow 2.0.7, Eclipse Web Platform with built-in Tomcat 6.0

Appreciate if you have any advice !
thanks in advance!!




My Service:
-----------
@Service
public class ProductFamilyService implements FactoryBean, InitializingBean, DisposableBean, ApplicationContextAware {
public List<ProductFamily> getAllProductFamilies () {
logger.debug ("if called");
return this.families.getFamilies();
}
}

My flow
-------
<on-start>
<evaluate expression="productFamilyService.getAllProductFami lies()" result="flowScope.families"/>
</on-start>

<!-- By default, the first state is the start state. -->
<view-state id="product" view="productFlow">
<transition on="addOptionGroup" to="addOptionGroup" />
<transition on="addProduct" to="addProduct"/>
</view-state>
.....

tested, POJO service works, but this service won't work:

public class MarketService implements FactoryBean, InitializingBean, DisposableBean, ApplicationContextAware {
...
}


any insight on this issue ?
