/**
 * A hook on the list of categories of the <code>CmsSearchParameters</code> 
 * (see <code>{@link org.opencms.search.CmsSearchParameters#setCategories(List)}</code>) 
 * that will set the page to display of the search parameters to start (1) whenever 
 * a change in the amount of categories takes place. <p>
 * 
 * This hook monitors the actions of the <code>{@link org.opencms.workplace.CmsWidgetDialog}</code>: 
 * During a request - response cycle it clears the list (prepareCommit)
 * of categories and adds all request parameters (actionCommitValue) to the list. <p
