Lines 770 to 786 in 8733f14

	else {
	boundary = xhr.getResponseHeader("Content-Type").split("boundary=")[1];
	parsedResponse = lrs._parseMultipart(boundary, xhr.response);
	statements = JSON.parse(parsedResponse[0].body);
	for (i = 1; i < parsedResponse.length; i += 1) {
	attachmentMap[parsedResponse[i].headers["X-Experience-API-Hash"]] = parsedResponse[i].body;
	}
	lrs._assignAttachmentContent(statements.statements, attachmentMap);
	result = new TinCan.StatementsResult({ statements: statements.statements });
	for (i = 0; i < result.statements.length; i += 1) {
	if (! (result.statements[i] instanceof TinCan.Statement)) {
	result.statements[i] = new TinCan.Statement(result.statements[i]);
	}
	}

When turning on attachment support the more link in the StatementResult is always null. Issue is in linked lines above. Code should be modified to grab the more value from the parsed JSON when doing attachments.
