Hi Aaron,
I guess there are various ways to design your JSF applications.
One of the simplest options is to put your ActionListener code into the
same class that backs up your JSF components, that is Customer.java.
By the way, looks like there should be another faces-config.xml entry for
the Events.java, right?
In any event, you might want to create your business object as a separate
Java class
and have Customer.java reference it. Then ActionListener will simply
retrieve values
of each component (name, address, etc) since they are accessible and update
your
business object with those values.
Anyway, this is how I would design my JSF apps, at least to get things
going.
Hope this helps,
Vadim.

10/28/2004 04:42 [WDSCI-L] JSF Model objects - how
PM do you fill them from a listener?
Please respond to

Status: Head bleeding from wall hitting
Ok, I have just about the simplest JSF app I can think of and what just
isn't making sense to me is how I update my "model" or "business logic"
object from an action listener that isn't part of the model object. I
am displaying an input text field where the user will enter a number.
When they hit the submit button an actionListener will get called (this
works). But how do I fill in my Customer java object from the action
listener method? The Customer object is registered in the
faces-config.xml as follows:
<managed-bean>
<managed-bean-name>customer</managed-bean-name>
<managed-bean-class>com.wgeb.customer.Customer</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
As you can see below I am filling in the outputFormat fields with
#{customer.xxxxx} which should map to the Customer object and pull
values from it.
CustIndex.jsp:
