Hi Mark,
The total number of items is an optional return value. If the repository
provides a value, OpenCMIS returns the number (>= 0). If the repository
does not provide a value, OpenCMIS returns -1.
See also the CMIS specification [1] and the OpenCMIS JavaDoc [2].
Why the Alfresco server doesn't provide the total number is a question
for Alfresco.

Hello,
I am using the Java OpenCMIS 0.8.0 SNAPSHOT from about a month ago against
an Alfresco 4 instance and all has been working just fine. I am using the
AtomPub binding. However, today after adding a some documents and writing
a test case to check that the number of records returned> 0, I got a
failure because the method: *queryResult.getTotalNumItems()* is returning a
*-1* even though there are, in fact, 2 items in the
ItemIterable<QueryResult> collection returned.
We have added a custom type namespace "acme:" to test adding some custom
properties to the cmis:Document object. This all works fine and the code
below works as long as the assertTrue() is not used because that returns
the -1 and reports the test failed. Although the
assertNotNull(queryResult) is technically invalid because even with NO
records found, one will not get back a null, it was a simple bypass to
confirm that in fact 2 rows get reported and the information printed by the
System.out is correct. I also confirmed through the Chemistry Workbench
running a Query, I DO get back 2 records as well.
The test code looks like this (some of it borrowed from the *GettingStarted
*application): We've written our own wrapper facade called CMISServices to
make the required calls via the OpenCMIS API code..
/**
* Test method
* @throws CMISServiceException
*/
@Test
public void testSearchRepositoryUsingEquals() throws
CMISServiceException {
String query = "SELECT * FROM acme:doc WHERE
acme:attachmentOID='1122334400556677' AND acme:category='Technical'";
ItemIterable<QueryResult> queryResult =
cmisServices.searchRepository(query); // calls
cmisSession.query(queryString, false) since searchAllVersions is NOT
supported on this version of AF 4
System.out.println("***results from query " + query);
assertNotNull(queryResult);
//assertTrue(queryResult.getTotalNumItems()> 0);
if (queryResult != null) {
int i = 1;
for (QueryResult qr : queryResult) {
System.out.println("--------------------------------------------\n" + i + "
, "
+
qr.getPropertyByQueryName("cmis:objectTypeId").getFirstValue() + " , "
+ qr.getPropertyByQueryName("cmis:name").getFirstValue()
+ " , "
+
qr.getPropertyByQueryName("cmis:createdBy").getFirstValue() + " , "
+
qr.getPropertyByQueryName("cmis:objectId").getFirstValue() + " , "
+
qr.getPropertyByQueryName("acme:attachmentOID").getFirstValue() + " , "
+
qr.getPropertyByQueryName("acme:attachmentType").getFirstValue() + " , "
+
qr.getPropertyByQueryName("cmis:contentStreamFileName").getFirstValue() + "
, "
+
qr.getPropertyByQueryName("cmis:contentStreamMimeType").getFirstValue() + "
, "
+
qr.getPropertyByQueryName("cmis:contentStreamLength").getFirstValue());
i++;
}
}
}
And here's what I get in the output (if I *don't rely on that
queryResult.getTotalNumItems()* method) ... there were 2 records as
expected.
***results from query SELECT * FROM acme:doc WHERE
acme:attachmentOID='1122334400556677' AND acme:category='Technical'

Is this something to open a JIRA record for or am I missing something?
Thanks
