Re: [Springframework-developer] StackOverflowError

[Thomas R. <tho...@tr...>]

Mark,

I guess we need a way for the container to figure out that you want a 
pair of objects referring to each other.

What happens if you do this:

<beans>

	<bean id="myClassA" class="com.foo.ClassA" singleton="false">
		<property name="classB">
			<bean class="com.foo.ClassB">
				<property name="classA">
					<ref local="myClassA"/>
				</property>
			</bean>
		</property>
	</bean>
	
</beans>
