Live Controller Considerations
Note the following considerations when working with live controller.
- APIs
- In the pilot, live controller attributes use a mix of API versions. You can use any live controller attribute that's available in your API version or lower.
- Expressions
- Live controller has limited support for expressions. Live controller tracks records attached to a standard controller or standard list controller. As a workaround, for all other records that display on your Visualforce page, you must use the records attribute to show the latest data.
- Limitations
- When you use live controller to subscribe to changes in multiple records, your page refreshes when any record updates. You can subscribe to a maximum of 50 records and five objects per Visualforce page.
- Unsupported Components
- These standard components do not work with live controller.
