Using an af:poll component to periodically refresh a table
The ADF Faces Poll component (af:poll) can be used to deliver poll events to the server as a means to periodically update page components. Poll events are delivered to a poll listener—a managed bean method—by referencing the method using the pollListener attribute. These poll events are delivered to the poll listener based on the value specified by the interval attribute. The poll interval is indicated in milliseconds; polling can be disabled by setting the interval to a negative value. An af:poll can also be referenced from the partialTriggers property of a component to partially refresh the component. In this case, a pollListener is not needed.
In this recipe, we will implement polling in order to periodically refresh an employees table in the page. By periodically refreshing the table, it will reflect any database changes done to the corresponding EMPLOYEES schema table in the database.
