Add record link to each part of a text string

Question

Hi Appian Community,
I have added into my interface a grid as shown below, which was called from a record type.

ID
    relateTo
Column 3
Column 4

001
003/004

002
007/004/005

003
001/002/006

004

005

006

007

This is the code that I wrote for column 2 (relatedTo) but didn't work. I used split () to split each row into an array of text IDs, then trying to add link to each of that ID. 
 a!richTextItem(     text: split(fv!row[recordtype.relatedTo], "|"),     link:  a!forEach(              items: split(fv!row[recordtype.relatedTo], "|"),              expression: a!recordLink(                                       label: fv!item,                                       recordType: recordType,                                       identifier: fv!item,                                       openLinkIn: "NEW_TAB"        )
    )
)
I want to add link to each ID in column 2 (ID that related to ID in column 1), so when I click any in that text string, I can be directed to the record for that certain ID. I think the identifier needs to be specific but not sure how to do it.
Thanks for your help, and appologise if the code is confusing...

You're missing the a!richTextDisplayField() - you can't just put a!richTextItem() by itself, it must be contained within a Rich Text Display Field.

Here's a working example if you want to check it out:

a!localVariables(
  local!data: {
    a!map(id: 1, value: "1/2/3"),
    a!map(id: 2, value: "4/5/6")
  },
  a!gridField(
    data: local!data,
    columns: {
      a!gridColumn(
        label: "ID",
        value: fv!row.id
      ),
      a!gridColumn(
        label: "Value",
        value: a!richTextDisplayField(
          value: a!forEach(
            items: split(fv!row.value, "/"),
            expression: {
              a!richTextItem(
                text: fv!item,
                link: a!recordLink(
                  recordType: 'recordType!{4c49fecf-28fc-447d-8acd-0547f4b609e6}PDL Case',
                  identifier: fv!item
                ),
                linkStyle: "STANDALONE"
              ),
              if(
                fv!isLast,
                "",
                " / "
              )
            }
          )
        )
      )
    }
  )
)

Hi,How about having the richTextItem in the loop?Let me make it more clear for you.you can have the richTextItem in the loop and add link to each text item you get out of the loop.Then the code would look this way.a!forEach(  items: split(fv!row[recordtype.relatedTo], "|"),  expression: a!richTextItem(    text: fv!item,    link: a!recordLink(      label: fv!item,      recordType: recordType,      identifier: fv!item,      openLinkIn: "NEW_TAB"    )  ))Please try it out!

ID	relateTo	Column 3	Column 4
001	003/004
002	007/004/005
003	001/002/006
004
005
006
007
