Hi guys, 

I created a visual force page that replaces view of a custom object. I now have tabs ....

My question is the following:

Lets say I have a custom object called X. How can I get a tab to display the "Event History" tab of this object ? I want to be able to view the field changes - which is in that related list? 

Thanks a mil

Stadler

PS: The code for my view update is as follow:

<apex:page standardController="Trading_Contract__c" showHeader="true">
