I currently have a custom button which I am using to launch a Flow by using a VF page as the source (which in tail launches an Apex Class). It works fine in a Page Layout, but I need to put it in a VF page now and I'm not sure how to do that.
This is the VF page which the button is using as a source :
<apex:page StandardController="Product__c" Extensions="New_ProductReview_With_Flow_Controller">
<flow:interview interview="{!myflow}" name="Product_Review" finishlocation="{!finishlocation}">
<apex:param name="VarProdRecID" value="{!Product__c.Id}"/>
</flow:interview>
</apex:page>
How would I include this custom button in another VisualForce page ?
Thank you very much for your help.
