Description copied from interface: Initiator

Does the initializes before the page is evaluated.

Note: when it is called, Page.getDesktop(), Page.getId() and Page.getTitle() all return null, since the page is not initialized yet. To get the current desktop, you have to use Execution.getDesktop() (from Executions.getCurrent()) instead. On the other hand, you can set the page's ID, title or style in this method (to override the declarations in the page definition) by Page.setId(java.lang.String), Page.setTitle(java.lang.String) and Page.setStyle(java.lang.String). In additions, Page.getRequestPath() and Page.getAttribute(java.lang.String, int) are all available.

Specified by:

doInit in interface Initiator

Parameters:

page - the page being evaluated

args - a map of arguments. Prior to 3.6.2, it is an array. To upgrade, use args.get("arg0") instead of args[0], args.get("arg1") instead of args[1] and so on. Of course, it is better to have a more meaningful name for each argument. If no argument is specified, args is an empty map (never null).

Throws:

Exception
