Packaged Visualforce pages are prevented from loading canvas apps that do not belong to the same package as the Visualforce pages
|Knowledge Article Number||000231526|
|Description||A canvas app embedded into an object's page layout cannot be displayed by an <apex:detail> component contained in a Visualforce page that is part of a package, unless the canvas app is part of the same package. If the canvas app is not part of the same package as the Visualforce page, the following error is displayed:
"Oops, there was an error rendering Force.com Canvas application [Canvas_App_Name]. Your browsing session has ended or is invalid. Please re-login to Salesforce.com again."
|Resolution||For security reasons, packaged (third party) Visualforce pages are prevented from loading canvas apps unless they are part of the same package as the Visualforce pages.|
