Query Filter not working - Lookup Community ID based on Community name

Question

I want to lookup Community ID based on the Community name. I tried the following code to filter the results and got a PTException. I'd appreciate any insight on to what I am doing wrong or a any other pointers to better implement this.
// Build a filter for querying the community id by name
Object[][] arrFilter = newObject[3][1];
arrFilter[0][0] = newInteger(PT_PROPIDS.PT_PROPID_NAME); //Operand
arrFilter[1][0] = newInteger(PT_FILTEROPS.PT_FILTEROP_EQ_NOCASE); //Operator
arrFilter[2][0] = newXPStringBuilder(_strCommName); //Value
IPTQueryResult qrCommunities = _ptSession.GetCommunities().Query(
PT_PROPIDS.PT_PROPID_OBJECTID | PT_PROPIDS.PT_PROPID_NAME, //Props
-1, //Folder to look in, -1 for "all"
PT_PROPIDS.PT_PROPID_NAME, //Property to order by
0, //Number of rows to skip, used for pagination
-1, //Max rows to return, used for pagination. -1 means no limit
arrFilter); //Filter to apply to results
Thanks.

Also if you dont want to use the server API you can use the code below with the SOAP interface
privatestringGetCommunityName(intiCommunityID)
stringsCommunityName = "";
//try to establish the remote session
try
if(log.IsDebugEnabled)
log.Debug("Start remote session attempt");
PortletRemoteSession = PortletContext.GetRemotePortalSession();
catch(Exception ex)
ErrorLabel.Visible = true;
ErrorLabel.Text = "Error esablishing remote session";
log.Error("Error esablishing remote session" + ex.Message);
if(log.IsDebugEnabled)
log.Debug(ex.Source);
log.Debug(ex.StackTrace);
//init the ObjectManager api to get the community name
IObjectManager oObjectManager = null;
try
if(log.IsDebugEnabled)
log.Debug("Start OBJ Man build");
//create the search request
oObjectManager = PortletRemoteSession.GetObjectManager(ObjectClass.Community);
//deine the admin folders to search
intfolderID = -1;
intstartRow = 0;
intmaxRows = -1;
//define the return result sort order a bit invalid in this case
ObjectProperty sortProperty = CommunityProperty.Name; ;//sort on the unique name
boolascending = true;
//what do we want back from this search
ObjectProperty[] propsToReturn = newObjectProperty[1];//choose to return specific properties
propsToReturn[0] = CommunityProperty.Name;
//build the query filter we only want the community name from the passed id
QueryFilter[] filters = newQueryFilter[1];//filter the results
filters[0] = newIntQueryFilter(CommunityProperty.ObjectID, Operator.Equals, iCommunityID);//filter results on community id
if(log.IsDebugEnabled)
log.Debug("Start OBJ Man query");
//do the search
IObjectQuery queryResults = oObjectManager.QueryObjects(folderID, startRow, maxRows, sortProperty, ascending, propsToReturn, filters);
if(log.IsDebugEnabled)
log.Debug("results returned = " + queryResults.GetRowCount());
//we should only ever get one result here
if(queryResults.GetRowCount() != 1)
log.Fatal("We have more than one community name result - warning Will Robinson warning");
thrownewException("We have more than one community name result");
//assign the name to the return var
IObjectQueryRow queryObject = queryResults.GetRow(0);
sCommunityName = queryObject.GetStringValue(CommunityProperty.Name);
catch(Exception ex)
if(log.IsDebugEnabled)
log.Debug("Search error - " + ex.Message);
ErrorLabel.Visible = true;
ErrorLabel.Text = ex.Message.ToString();
finally
//clean up
if(oObjectManager != null)
oObjectManager = null;
//and return the community name
returnsCommunityName;
