Hello again, everybody.
I've encountered another additional problem. When I try to retrieve a subarray using pva://Array_of_elements.VAL[3:7], the value in the PV Table is 'PV Error'.
I've also tried without 'VAL' and with other punctuation marks like parenthesis without success.
In addition to that, I came across an answer to a similar question (https://epics.anl.gov/tech-talk/2022/msg00529.php) where it suggested trying with the array filters of EPICS 3, but I think that's what I'm doing, so maybe is it a problem with my Phoebus build?
Any help is welcome.
Thanks, Eusebio.

Hello everybody.
I've a little question that it seems obvious.
I have a PV define as an array that looks like this:
record(aai, "Array_of_elements") { field(DESC, "Test") field(FTVL, "INT64") field(NELM, "20") }
If I want to access one specific element of that array, for example the 7th, I can just do this:
pvmonitor Array_of_elements.VAL[7]
However, in Phoebus' PV Table, I'm trying to do the same, with something like pva://Array_of_elements.VAL[7], but I'm always getting the entire array and not the specific element, how can I solve it?
Thanks in advance, Eusebio.
