Class DynTabTracker

java.lang.Object
dyntabs.DynTabTracker
All Implemented Interfaces:
Serializable
@Named @ViewScoped public class DynTabTracker extends Object implements Serializable
Tracks the state of all dynamic tabs in the current view (session).

This is a @ViewScoped bean that maintains the complete list of DynTab instances (both active and inactive), the tab-by-ID lookup map, the selected tab ID, and the count of active tabs.

Tab list structure:

  • tabList[0..numActive) contains the active (visible) tabs
  • tabList[numActive..n) contains the inactive (placeholder) tabs

When a tab is closed, it is not removed from the list but moved to the inactive region. When a tab is opened, an inactive placeholder is reused and moved to the active region.

Initial tabs are loaded in init() based on DynTabConfig.getInitialTabNames(), using DynTabRegistry to create the DynTab instances.
