We're not able to reproduce this in testing from what you've said, but the stacktrace indicates an obvious issue.

Can you show a simple test-case we can run that shows the issue? Just an onModuleLoad() that sets up your calendar's settings and uses a clientOnly dataSource for data will suffice.

Some additional information:
Using a RestDataSource()
setDataFormat(DSDataFormat.XML)

Things I've tried:
1. Replaced the Calender() with a ListGrid(), to make sure it's not a problem with the datasource. It worked fine.
2. Create a small testcase with attached xml data file (timesheet.xml 104 records), which worked fine (except when I used result.setClientOnly(true))

Code:

	    RestDataSource result = new RestDataSource();
	    result.setDataFormat(DSDataFormat.XML);
        //result.setClientOnly(true);
	    OperationBinding fetch = new OperationBinding();  
        fetch.setOperationType(DSOperationType.FETCH);  
        fetch.setDataProtocol(DSProtocol.POSTMESSAGE);
        result.setOperationBindings(fetch);
        DataSourceIntegerField id = new DataSourceIntegerField("id", "Id");
        id.setPrimaryKey(true);
        DataSourceTextField name = new DataSourceTextField("name", "Name");
        DataSourceTextField description = new DataSourceTextField("description", "Description");
        DataSourceDateTimeField startDate = new DataSourceDateTimeField("startDate", "startDate");//NOTE field is case sensitive
        DataSourceDateTimeField endDate = new DataSourceDateTimeField("endDate", "endDate");//NOTE field is case sensitive
        DataSourceBooleanField canEdit = new DataSourceBooleanField("canEdit", "canEdit");//NOTE field is case sensitive
        DataSourceTextField eventWindowStyle = new DataSourceTextField("eventWindowStyle", "eventWindowStyle");//NOTE field is case sensitive
        DataSourceIntegerField userid = new DataSourceIntegerField("user_id", "User ID", 25);
        DataSourceIntegerField groupid = new DataSourceIntegerField("usergroup_id", "Group ID", 25);
        DataSourceIntegerField max_bookings = new DataSourceIntegerField("max_bookings", "Max Bookings", 25);
	    result.setFields(id, name, description, startDate, endDate, canEdit, eventWindowStyle, userid, groupid, max_bookings);
	    result.setFetchDataURL(GWT.getHostPageBaseURL()+"data/timesheet.xml");	
	    
	    Calendar calendar = new Calendar();
        calendar.setDataSource(result);
        calendar.setAutoFetchData(true);
        calendar.draw();

So it would seem that the problem comes in when trying to retrieve the second set of DataPageSize data, from the server to update the current Calendar view.

Please let me know if there's more info you need.

We've lost track somewhat of what actual bug you're reporting here.

It seems as though you're saying that your sample code works fine, unless you add setClientOnly(true), right?

If that's the case, then yes, that's expected behavior - your code doesn't set testData or cacheData on the DataSource, and that's required for clientOnly dataSources.

You could probably also use DataSource.getClientOnlyDataSource().
