Converter exception when using a factory?
We have this object that exists in the servlet session that I want to make available to inject into other Seam components. So I tried to create a factory pattern object:
public class SessionObjFactory {
public ParamBean getParamBean()
{
return (ParamBean)Contexts.getSessionContext().get(SessionConstants.PARAMS);
}
public void setParamBean(ParamBean params)
{
Contexts.getSessionContext().set(SessionConstants.PARAMS, params);
}
}and specified a SessionObjFactory.component.xml (wanted to use the auto-create option which does not seem to be available in the Factory annotation).
<component>
<factory name="paramBean" value="#{sessionScope.paramBean}" scope="session"/>
</component>
on startup I see the following exception:
17:11:05,069 ERROR [[/]] Exception sending context initialized event to listener

What is going on I thought the factory pattern can be used to create any Pojo object? I can't find any documentation for having to create some Converter object for factories?
