Hi. Solution for that problem is indeed comparator class, but if you want to
sort page templates by order that they appear in config, it's a little more
difficult. In comparator class you get not a nodes to compare, but
SelectFieldOptionDefinition objects, which have more-less just node id (not
even path).
In my case that code solved a problem:
[code]public final class PageTemplateComparator implements
java.util.Comparator<SelectFieldOptionDefinition> {
public static final String ABSOLUTE_PAGES_PATH =
"/modules/myWebsite/templates/";
public static final String CONFIGURATION_REPOSITORY = "config";
private static final Logger LOG =
LoggerFactory.getLogger(PageTemplateComparator.class);
@Override
public int compare(SelectFieldOptionDefinition o1,
SelectFieldOptionDefinition o2) {
try {
String subpath =
o1.getValue().substring(o1.getValue().lastIndexOf(':')+1,o1.getValue().lastIndexOf('/')+1);
Node parentNode = JcrUtils.getNodeIfExists(ABSOLUTE_PAGES_PATH +
subpath, MgnlContext.getJCRSession(CONFIGURATION_REPOSITORY));
NodeIterator i = parentNode.getNodes();
List<String> nodeNamesList = new ArrayList<>();
while (i.hasNext()) {
Node node = (Node) i.next();
nodeNamesList.add(node.toString());
}
String path1 =
o1.getValue().substring(o1.getValue().lastIndexOf(':') + 1);
Node node1 = JcrUtils.getNodeIfExists(ABSOLUTE_PAGES_PATH + path1,
MgnlContext.getJCRSession(CONFIGURATION_REPOSITORY));
int index1 = nodeNamesList.indexOf(node1.toString());
String path2 =
o2.getValue().substring(o2.getValue().lastIndexOf(':') + 1);
Node node2 = JcrUtils.getNodeIfExists(ABSOLUTE_PAGES_PATH + path2,
MgnlContext.getJCRSession(CONFIGURATION_REPOSITORY));
int index2 = nodeNamesList.indexOf(node2.toString());
return index1 - index2;
} catch (RepositoryException e) {
LOG.error("Error occurred during data fetch from repository " + e);
return 0;
}
}
}[/code]
