At times, it may be necessary to perform some initialization functions when the map first loads. To accomplish this, a page loaded into the task pane can hook into the standard map initialization process.
For example, when a browser first connects to an Infrastructure Map Server site, it specifies a web layout. The site uses this layout to determine which Viewer components to enable and which map to display in the map area. At the time that the task pane first loads, the map name is not yet known. It may be required for some operations, though.
