Check entries's count of a list in Decide Activity

If I'm working with a Global List and need to check if it's empty or count the entries in a Decide Activity, but I don't have a partition ID, what should the checking clause be in the Decide Activity? None of the options below seem to work. Also, could you explain what "processFlow" refers to?

List.entries().length

OR

getstat(getactivity(processFlow, "List"), "PartitionContent", STAT_CURRENT, 0, partitionID) https://answers.flexsim.com/questions/32530/list-entry-count-by-partition-id.html

Also, how I check entries of two Lists at the same time?

FlexSim 24.0.1

list list entries

Let we say, you call your list "myList".

Then

List("myList").entries().length

returns number of entries.

I assume you want to check entries of a global list, without knowing actually the partition ID. You find a global list still in your model tree. And you find all entries and their partitions, too.

@Joerg Vogel yes, it's a globall list and there is no partition ID on my list.

I want to know how I can check the count of entries of a global list in a Decide Activity, the link you've shared doesn't answer to this question.

You said in your question you just wanted to know if it was empty...

Instead of a decide can you not just use a pull activity set to leave entries on the list and with a timeout to send the token to port 2 if it fails to pull?

@Jason Lightfoot I understand that strategy, but I need to know on implementing it within a Decide Activity. There's a scenario where the token is directed to connector 2 due to a Max Wait Timer setting. If it fails to retrieve an item from the list, it moves to a Decide activity. Here, it needs to count the entries from a different list in another process flow before making a decision. Is it feasible?
