Bug with List and on Push Event

[sebastian_hemmannE3JAU]

[ FlexSim 20.1.2 ]

Hi,

I´m pushing a token on a list and listen with an event-triggered-source to the "on push" of the list.

It seems as if there is a bug. The token in the Push to List activity is not going on.

Tried it out in some older versions. Always the same.

@sebastian.hemmann Hi Sebastian, if you put a breath(a delay with 0.0) between the source and the Pull from list it works. Problem most likely is that when OnPush event is triggered the token is not on the list yet or not completely on the list. Why the pull works I don't know but something in the chain of event needs some time to fix it. (But I'm not sure what problem you are solving here? Because this doesn't look like the best possible solution...)

Hi Steven, thanks for the fast reply. Yes I already found some ways to make it not happen (e.g. listening to the OnEntry of the Push to List). And you also are right, there might be not many cases to use it exactly this way. A client figured this out and I just shared the issue because I can´t estimate what other cases this maybe has an impact for. Or maybe anybody knows it´s a feature 🙂

This is a feature of how Wait for Event works: https://docs.flexsim.com/en/20.1/ModelLogic/AdditionalConcepts/TroubleshootingProcessFlows/#delays

@phil.bobo Hi Phil, thank you for the hint. What is the preferred way to release the tokens out of the "Push to List" activity anytime?
