Trigger prototype and see operational data of other prototype

[Brambo]

In my discovery rule I create to items
1 containing a numeric value
1 containing a string value
In my trigger prototype I use the numeric to create expression.

last(/templatename/component.[{#NAME}],#2)=1

And this works fine for creating and resolving of the problems.
However I would like to have the item value of the item with key:
I tried:

{?last(/templatename/component.description.[{#NAME}])}

and

{?last(//component.description.[{#NAME}])}

In the Operational data field but both don't seem to work? The {ITEM.VALUE} works just fine.

{?last(/templatename/component.description.[{#NAME}])}

and

{?last(//component.description.[{#NAME}])}

Those expressions are using an old syntax. You should build your trigger expressions in the same way you did in the first code.

I'm not entirely sure about what you're trying to do since the first expression was working. So, if you can explain your objective a bit more, maybe I'll be able help you achieve what you need.

Best regards.

Yeah it seems the {? } part wasn't needed, I copied this from a calculated item and now tested it without the brackets and ? and the data is shown with the value when the problem is created.
It doesn't dynamic update but as far as I know that is by design
