Pull Bug in Conveyor Entry Transfers?

It seems that there is a bug with the pull mechanism on conveyor entry transfers. Nothing is pulled, although the requirement is fulfilled. In attached model 20160914-pullbugconveyor-1620.fsm I want to pull specific itemtypes from a rack, but neither of the conveyors pulls any item. I also tried in 16.1.1 and with a processor instead of the rack and neither one worked.

Thanks Ralf

The code header for the Pull Requirement field is incorrect based off what is actually being passed into the function. This is the correct header:

treenode current = param(1);
treenode item = param(2);
int port =  param(3);

We'll get this fixed on our end, but for now you can just change out the first 3 lines and your model will work fine.

Double click on Rack, Rack properties window will open,In the flow tab just change the send to port option as By expression instead of First Available.

Shashikumar,

that is a workaround for this simple model but the goal of the post was to report the (supposed) bug. I have changed the model so it is more obvious.

Thanks Ralf
