Page Service 

The page service provides information about the page in which the application is running, and enables you to perform the following tasks:

●      Getting a list of the atomic names of the visible iViews in the page.

You may want to use this method to avoid updating the user interface of an iView when it is not visible.

IWDPageService pageService = (IWDPageService)     WDPortalUtils.getService(WDPortalServiceType.PAGE_SERVICE); // String array receives iView names String[] iViews = pageService.getVisibleIViews();

●      Hiding/showing iViews in the page

IWDPageService pageService = (IWDPageService)     WDPortalUtils.getService(WDPortalServiceType.PAGE_SERVICE); // display iView Search pageService.showIView("Search"); // hide iView Details pageService.hideIView("Details");

Changes to the visibility of iViews are not saved. When a user refreshes the page, the original settings are restored.
