Bug 82231 [build path] Hard to find type restriction compiler problem preferences
I20050104-1600 There compiler preference page contains a Warning/Error node with many sub-entries . I tried to find where I could change the 'warning' for the access of internal types to 'error'. No luck until I realized that the Build node also contains Warning/Error settings.

selElement.setAttribute(CPListElement.ACCESSRULES, dialog.getAccessRules());
			selElement.setAttribute(CPListElement.COMBINE_ACCESSRULES, new Boolean(dialog.doCombineAccessRules()));
			fProjectsList.refresh();
			fClassPathList.dialogFieldChanged(); 
		}
	}
		
	private void editElementEntry(CPListElement elem) {
		CPListElement[] res= openProjectDialog(elem);
		if (res != null && res.length > 0) {
			CPListElement curr= res[0];
			curr.setExported(elem.isExported());
			fProjectsList.replaceElement(elem, curr);
		}		
			
	}
	
	private Shell getShell() {
		if (fSWTControl != null) {
			return fSWTControl.getShell();

	private CPListElement[] openProjectDialog(CPListElement elem) {
		
		try {
			ArrayList selectable= new ArrayList();
			selectable.addAll(Arrays.asList(fCurrJProject.getJavaModel().getJavaProjects()));
			selectable.remove(fCurrJProject);
