Yes, this is correct. <AddItemToList> and <ForEachItemInList> are tags in the Script Language. .Count is a method in our Path Language and cannot be used with these list tags. There is now a configuration example article to illustrate how to use <If> to see if a list is empty: Checking if a List is Empty

So, ".Count" is not available for a list, I interpret. Is this described anywhere in the user documentation and if not why? Any way to check by an <If> statement if the list is empty?

Hi Jakub,
The concept of the list is quite old and limited. It has been introduced many years ago to support some use cases in Report.
So, my recommendation is to use a Variable instead of a list, then you can apply all the Path query methods e.g. Count.
Down you can see an example of how to convert from using a List to a Variable, then how to check if a variable is empty.
I'm trying to check if a list is empty. The thing is that.Countwill not work in my case since I'm trying to do a checkout onlocallist that exists only within the sandbox script body (I create the list using <AddItemToListUnique> )

Hello Jakub,
Based on my knowledge there is NO progress with this wish. However, could you please describe your use case, is it something similar to use case above or something else?

Today this is not possible.
However it would be nice to have a concept in the path language that is similar to lists i.e. a variable that you can add things to as you go.

I’m trying to add items into a list and then use the Path language to get the value of this list. For example,
Instead, I want to use the path language to get the value of the list, for example
Is that possible?

Using a List example:
Convert the above example to use a Variable:
Then you can check if the variable is empty using .Count
or using =[]

Well, the issue is the same as here: https://support.systemweaver.se/support/discussions/topics/31000002052
