Thanks but... this is what I knew so far :-)
What I want is not sharing an ENTIRE bean, just ONE variable. (a
managed property)
Is this possible as well?
Thought of these 2 possibilities: (donno whether it would work/
whether at least one of them is correct)
<managed-bean>
<managed-bean-name>A</managed-bean-name>
<managed-bean-class>...</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</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> <!-- Name of
the very same var in bean B-->
<value>#{beanA.varA}</value> <!-- referencing this way
allowed?-->
</managed-property>
</managed-bean>
Or:
<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> <!-- Name of the var
in bean A -->
<value>what to put here if the var is only defined at
runtime? It appears to be a required element </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> <!-- Name of
the very same var in bean B-->
<value>#{varA}</value> <!-- referencing of a managed
prop of another bean in this way allowed?-->
</managed-property>
</managed-bean>
Any ideas?

Hi,
Short question: (thought of another solution)
Is this the proper way of passing just one variable from one
backing bean to another, or is there a better way? (I'd just like
to avoid sharing the entire bean, which you usually see)
So if e.g.
- bean A has varA
- bean B wants to access just this ONE variable from bean A
--> Is this correct? (or is there a better/proper way)
<managed-bean>
<managed-bean-name>A</managed-bean-name>
<managed-bean-class>...</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<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> <!-- Name of
the very same var in bean B-->
<value>#{beanA.varA}</value> <!-- referencing this
way allowed?-->
</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
