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.
