Visualforce Considerations
Keep the following considerations in mind when using the <apex:canvasApp> component:
- The <apex:canvasApp> component is available only in organizations that have Canvas enabled and in Visualforce pages at version 27.0 or higher.
- If you include a canvas app on an object detail layout, you must provide the height of the canvas app in the page layout as well as in the <apex:canvasApp> component.
- Location—If the canvas app is in a Visualforce page, then the Environment.displayLocation field contains the value Visualforce.
