Show information from related object in VisualForce

Hi all. Im creating a wizard with VisualForce were, to put an example, I'm populating information from a Customer and the product it bought. So, in the first step we load the information related to the Customer (Customer__c), in the second page we load the information for each of the product he/she bought (Product__c), and in the third page I want to show the summary of all this steps.
So, my problem comes at this step, were I want to show, for each of the products, the Product Type (Product_Type__c) they belong to (information that was loaded though a lookup in the step 2).
so, the Visualforce code that I'm trying to use is:

<apex:repeat value="{!products}" var="item">
   <apex:outputText value="Article Number"/>
   <apex:outputText value="{!item.Article_Number__c}"/>
   <apex:outputText value="Product Type"/>
   <apex:outputText value="{!item.Product_Type__c.Name}"/>
</apex:repeat>

When trying to save this I get: Error: Unknown property 'String.Name'
When I remove the .Name, what I'm showing is the Id of the Product_Type__c chosen.
So, how can I iterate through the list of product and for each of it show the Product_Type__c.Name ?
Thank you in advance!

try Product_Type__r.Name

note the r tells salesforce it's a related name.

thx

It doesn't work, becuase it seems that the relationship does not exists until the object is saved, so in that place is showing a blank field. I know the Product Type Name exists, because is what is shown in the lookup.

hmm ok you'll need to possibly use transaction control in your apex for the vf to manage this then - that way the relationship should be establish and in the event you change your mind you can do a rollback.

this might help:

Mmm, I don't think this should be the solution to show the summary information. There should be a way of showing this information before saving it.
