Refresh issue with a!richTextItem on variable refresh

Hi,
bellow an example how you can append new item into your surveyDoc array and the rich text field will update:

a!localVariables(
  local!languageData:{survey:"some language"},
  local!surveyDoc:{appianDocumentId:101457},
  a!formLayout(
    label:"Dummy",
    contents:{
      a!richTextDisplayField(
        label: "",
        labelPosition: "COLLAPSED",
        value: {
          a!richTextItem(
            text: { index(local!languageData, "survey", {}) },
            style: "STRONG"
          ),
          " : ",
          if(
            count(local!surveyDoc) > 0,
            a!forEach(
              items: local!surveyDoc,
              expression: {
                a!richTextItem(
                  text: document(
                    tointeger(fv!item.appianDocumentId),
                    "name"
                  ) & char(13),
                  link: if(
                    rule!APN_isBlank(fv!item),
                    null,
                    if(
                      true,
                      a!startProcessLink(
                        processModel: cons!PROCESS_MODEL,
                        processParameters: {
                          documentId: fv!item.documentId,
                          appiandocid:fv!item.appianDocumentId
                        }
                      ),
                      a!documentDownloadLink(
                        label: document(tointeger(fv!item.appianDocumentId),"name"),
                        document: fv!item.appianDocumentId
                      )
                    )
                  )
                )
              }
            ),
            a!richTextItem(text: "Not Available")
          )
        }
      ),
      a!buttonLayout(
        secondaryButtons: {
          a!buttonWidget(
            label:"Update survey doc array",
            value:null,
            saveInto:a!save(
              local!surveyDoc,
              fn!append(
                {local!surveyDoc},
                {appianDocumentId:119534}
              )
            )
          )
        }
      )
    }
  )
)
