Bug 21583 Generate Javadoc won't link prereqed projects
In the export wizard for generating javadoc, there is no easy way to link the javadoc from a prereqed project. The wizard has a screen for linking in javadoc from libraries included in the classpath, but projects in the classpath do not show up. I got a temporary workaround from the news group. Just add a "-link URL_TO_OTHER_PROJECT_JAVADOC" in the javadoc options page, but there should be an easier way to do this.

		fTempLinks= createTempLinksStore();
		UpdateCheckedListGroup();

	private Map createTempLinksStore() {
		Map temp= new HashMap();
		IProject[]  projects= fStore.getRoot().getProjects();
		for (int i = 0; i < projects.length; i++) {
			IProject iProject = projects[i];
			IJavaProject javaProject= JavaCore.create(iProject);
			if(javaProject!= null) {
				String links= fStore.getLinks(javaProject);
				temp.put(javaProject, links);
			}
		}
		return temp;
