First you have to configure the tab which should be displayed in the work area. This must be an Panel or any extended one. CoreMedia recommends that you configure your tab as a separate class. The rationale for this will be described below. In the example there are two such components: BrowseTab.ts and CoreMediaTab.ts (where the latter one uses the first one). Both have a configuration parameter url which is the key to persisting tab state across sessions and website reloads as explained below in Section 9.17.4, “Storing the State of a Work Area Tab”.
