+1Hi!
I have a list, containing between 5 and 50 values (varying). How can I append a value to this list? I can only assume there has to be a non-pythonic way, but I struggle to find one. My approach was to use AttributeCreator, but I can't dynamically specify the position in the list. Had the list size been fixed, then that's a solution - but not in this case.
Any ideas?

You can use the ListElementCounter to find the last position, which you can then use in the AttributeCreator. Example, assuming your list is called "list{}":

However, I can't get it to "evaluate" properly? Instead, it creates an attribute called list{@Value(_element_count)}

For what it's worth, if you want to avoid to expose it, and also do not use Python, Tcl scripting would be an alternative. Assuming an attribute called "_newValue" stores the new value to be appended to the "_list{}".
Tcl Expression for a TclCaller
FME_SetAttribute _list{[FME_Execute NumElements _list{}]} [FME_GetAttribute _newValue]
@Tcl2("FME_SetAttribute _list{[FME_Execute NumElements _list{}]} @Value(_newValue)")
+5Hi All,
I am working with lists and require some guidance on the below scenario
I have list which contains 'n' elements. I would like to add a sub-element to each element in the list.
Assuming my list name called as "list{}"
Example: (My list currently looks like this)
List{0}
element1
element2
element3
List{1}
element1
element2
element3
List{2}
element1
element2
element3
List{n}
element1
element2
element3
I would like to add new sub-element called "element4" at the end of each list element (i.e., add "element4" as sub-element below "element3" )
Expected Output (I would like to achieve something like below)
List{0}
element1
element2
element3
element4
List{1}
element1
element2
element3
element4
List{2}
element1
element2
element3
element4
List{n}
element1
element2
element3
element4
Would really appreciate your help in achieving the above expected output.
Thanks
