How to Send or Pull more then one itemtype

Hallo

I have to send or pull flowitems based on their ItemType to specific Processors

Prozessor1 should get ItemType 1 or 2
Prozessor2 should get ItemType 1 or 2
Prozessor3 should get ItemType 3 or 4
Prozessor4 should get ItemType 3 or 4

I was not able to program that or in to the Pull Requirement. How can I do that?

@Marc B

I have attached the model with the changes.

You can specify the item types in Array of ItemTypes.

Hope this works for you

Thanks

I have an additional question to the array solution:

If I prefer to control the flow over the output (send to port), how I have to write the code?
I tried this one, but it doesn't work:

Object item = param(1);
Object current = ownerobject(c);

Array port1 = [1, 2, 3];
Array port2 = [4, 5, 6];

int condition = /** \nCondition: *//***tag:expression*//**/getitemtype(item) == 1 || getitemtype(item) == 2/**/;

return condition?port1:port2;

One way to do this is to push the items onto a list and partition them by type, and then have your ports pull from the list by partition ID.

Hope this helps.

In order to pull from two different Types, you can use the pull requirement "Range of Item Types" and set the limits to 1 and 2, or 3 and 4.

I've attached your file with these changes made. I also removed the sorting processor, as the processors can pull directly from the queue. Hope this helps.
