Sharing just a bean VARIABLE between 2 managed beans - Howto?

[Wolf Benz <eu...@gmail.com>]

Hi,

I often see that beans get injected in one another (as in: the ENTIRE  
bean is injected in another bean as a variable), but is this also  
possible:

- declare a variable in one bean
- access just this ONE variable from another bean?

So suppose bean A has a variable varA and bean B wishes to access  
just this variable.
--> Is smth like the following possible:

	<managed-bean>
		<managed-bean-name>A</managed-bean-name>
		<managed-bean-class>...</managed-bean-class>
		<managed-bean-scope>session</managed-bean-scope>
		
		<managed-property>
			<property-name>varA</property-name>
			<property-class>java.util.ArrayList</property-class>
			<value>? what to put here if the content is not fixed but defined  
@ runtime? </value>
		</managed-property>
	</managed-bean>
	
	<managed-bean>
		<managed-bean-name>B</managed-bean-name>
		<managed-bean-class>...</managed-bean-class>
		<managed-bean-scope>session</managed-bean-scope>

		<managed-property>
			<property-name>beanB_varA</property-name>
			<value>#{varA}</value>
		</managed-property>
	</managed-bean>


... Or does one really have to reference the entire bean and then  
perform a getter?
So in this case: reference entire bean A from Bean B and in bean B's  
code do beanB_varA = getBeanA().getVarA() ?

Thx,
Wolf
