We want to override the VF page for adding products to an opportunity.

We added 3 custom fields to our Product2 object for choosing the products. These are picklist fields with field dependencies in order to filter our list of products. The content of “Product Sub-Group” depends on a selection of “Product Group” whereby “Product Group” depends on the selection of “Main Article Group”.

This is very simple to develop if we use a variable p of type Product2 which is declared in the controller extension and accessed in the VF Page with <apex:inputField..> .  See this little code:

public without sharing class yAddProducts { public Product2 p {get;set;} public yAddProducts(ApexPages.StandardController controller) { p=new Product2(); } } <apex:page standardcontroller="Opportunity" extensions="yAddProducts"> <apex:Form > <apex:PageBlock > <apex:outputText value="{!$ObjectType.Product2.Fields.yMainArticleGroup__c.Label}"/><BR/> <apex:Inputfield value="{!p.yMainArticleGroup__c}"/><BR/> <apex:outputText value="{!$ObjectType.Product2.Fields.yProductGroup__c.Label}"/><BR/> <apex:inputField value="{!p.yProductGroup__c}"/><BR/> <apex:outputText value="{!$ObjectType.Product2.Fields.yProductSubGroup__c.Label}"/><BR/> <apex:Inputfield value="{!p.yProductSubGroup__c}"/><BR/> </apex:pageBlock> </apex:Form> </apex:page>

It’s possible to select values from the picklist with dependencies. Everything works as expected if we are logged in as system administrator.  But our users have only read permissions for the Product2 Object.  These users don’t see any listbox for the picklists at the VF page. The problem exists because of the permissions, but our users shall not be allowed to create, update or delete products. Note: we don’t want to save the product in variable p, we only need this as a "template" for the comfortable input with dependencies of the list boxes to use it as a filter. Of course, we could develop the dependencies of the picklist values with string arrays or whatever, but this is lot of work, especially if values in the picklist fields and their dependencies will change some day. Any idea how I can use <apex:inputField..> for an SObject independent of the given CRUD permissions for the logged in user?

Thanks,
