JS layout manager
var layout = {
layoutMgrData : "layoutMgr",
instances : [],
_addInstance : function(instance) {
var added = false;
// Need to ensure the instances are sorted outer-to-inner for
// any containment relationships. That way we layout the broadest
// element and then allow the inners to adjust accordingly.
var len = layout.instances.length;

When using a Jackson JsonGenerator directly (the streaming API), make sure to call close() when finished. Otherwise, the content will be impartial.
JsonFactory jsonFactory = new JsonFactory();
StringWriter prefValue = new StringWriter();
try {
JsonGenerator jsonGen = jsonFactory.createJsonGenerator(prefValue);
jsonGen.writeStartArray();
for (int i = 0; i < source.getSize(); ++i) {
jsonGen.writeString(source.getElementAt(i).getAbsolutePath());
}
jsonGen.writeEndArray();
jsonGen.close();
