Another Form Question

Looks like I'm striking out big time with this form I'm working on.  
Sorry for all the traffic.  Apparently, my understanding of the form 
processing cycle is a bit off, because I can't get the following 
scenario to work.

I have something like:

<form jwcid="@Form" listener="ognl:listeners.create" 
delegate="ognl:beans.delegate">
	<tr jwcid="@BillingInfo" customer="ognl:customer"/>
	<tr jwcid="@ShippingInfo" customer="ognl:customer"/>
    . . . .
    . . . .
</form>

And ShippingInfo.jwc has something like the following:

     <parameter name="customer" type="com.servprise.www.models.Customer" 
direction="auto" required="yes"/>

     <bean name="required" 
class="org.apache.tapestry.valid.StringValidator" lifecycle="page">
         <set-property name="required" expression="true"/>
     </bean>

     <component id="shippingName" type="ValidField">
         <static-binding name="displayName" value="Shipping Name"/>
         <binding name="validator" expression="beans.required"/>
         <binding name="value" expression="customer.shippingName"/>
     </component>


Now the problem is, in the create() listener, I assign some values to 
the shipping fields in the customer object.  Then I return from the 
form, causing the page to be redisplayed.  When it redisplays however, 
the items in the ShippingInfo component are not updated.  Well, 
anything that uses validation isn't updated -- "regular" components 
seems to update fine.  This obviously isn't what I would like, but I 
haven't been able to come up with much of a solution.

Any thoughts?

Thanks,
Kevin

Yes, so the values aren't overwritten when the page renders.

Hi,

Is the customer property of the page persistent?

Replying to myself on this.  Apparently if a valid component is in error,
its bound value can't be changed.  Clearing the delegate errors before
returning from the listener did the trick.
