I've had instances in using an iterator with published output with a queue patch inside, where the image data on the output of the queue was being converted to some unusable type that was still an image data type, yet causing there to be no evaluation past the output. My solution ended up being to construct a queue with JavaScript, which worked correctly.
I'm not able to look at any attachments that have been posted, as I'm mobile right now, but I'm throwing it out there in case it ends up being a viable solution for you. -George Toledo On May 26, 2010 1:18 PM, "Roger Jones" <[email protected]> wrote: Im still having problems with this. When I try to read the port I get a message that there is no output named "myportname" I tried to register for a notification with - (void) QCViewDidStartRenderingNotification:(NSNotification*)notification { NSLog(@"QCViewDidStartRenderingNotification"); } but I never get the notification. I also attempted to read the port inside if ([visView isRendering]) { groupArray = [visView valueForOutputKey:@"groupList" ofType: @"NSArray"]; but it throws an exception. So I think the composition is rendering but the port is just not available yet. How can I test for the availability of a port in a qcView?
