Please share the code snippet from the interface.

Hello mollyn126 

Please share the code snippet from the interface.

Here is the code for my interface grid:

a!gridField(label: "",
      labelPosition: "ABOVE",
      pageSize: local!selectedPageSize,
      data: 'recordType!Record',
      columns: {
        a!gridColumn(
          label: "Case Number",
          sortField: 'recordType!caseNumber',
          value: fv!row[recordType!caseNumber],
          align: "CENTER"
        ),
       a!gridColumn(
          label: "Case Number",
          sortField: 'recordType!caseNumber',
          value: fv!row[recordType!caseNumber],
          align: "CENTER"
        ),
        a!gridColumn(
          label: "Customer",
          sortField: 'recordType!Customer',
          value: fv!row[recordType!Customer],
          align: "CENTER"
        ),
        a!gridColumn(
          label: "Created Date",
          sortField: 'recordType!createdDate',
          value: fv!row[recordType!createdDate],
          align: "CENTER"
        ),
        a!gridColumn(
          label: "Completed Date",
          sortField: 'recordType!completedDate',
          value: fv!row[recordType!completedDate],
          align: "CENTER"
        )}
        )

And is the code for the query to view. I just fixed the error by changing totalCount to length(local!dataSubset.data) then the grid displayed all data without any error but I couldn't understand why...

a!localVariables(
  local!dataSubset: a!refreshVariable(
    refreshAlways: rule!GBL_replaceNull(nullableValue: ri!refreshAlways, replacementValue: false),
    refreshInterval: ri!refreshInterval,
    value:rule!AAA_CMN_General_queryEntityHelper(
      refreshAlways: rule!GBL_replaceNull(nullableValue: ri!refreshAlways, replacementValue: false),
    refreshInterval: ri!refreshInterval,
    fetchTotalCount: ri!fetchTotalCount,
    entity: cons!myView,
    columns: ri!columns,
    logicalExpression: a!queryLogicalExpression(
      ignoreFiltersWithEmptyValues: true,
      operator: if(
        rule!AAA_CMN_IsBlank(
          ri!filterOperation
        ),
        "AND",
        ri!filterOperation
      ),
      filters: append(
        {
          a!queryFilter(
            field: "caseId",
            operator: "in",
            value: ri!caseId
          )
        },
        ri!filters
      ),
      logicalExpressions: ri!logicalExpression
    ),
    pagingInfo: if(
      isnull(
        ri!pagingInfo
      ),
      a!pagingInfo(
        startIndex: 1,
        batchSize: -1,
        sort: {
          a!sortInfo(
            field: "caseId",
            ascending: true
          )
        }
      ),
      ri!pagingInfo
    )
  )
  ),
  a!dataSubset(
    startIndex: local!datasubset.startIndex,
    batchSize: local!datasubset.batchSize,
    sort: ri!pagingInfo.sort,
    totalCount: length(local!datasubset.data),
    identifiers: local!datasubset.identifiers,
    data:  fn!cast(
      fn!typeof(
        ri!cdt
      ),
      fn!property(
        local!dataSubset,
        "data",
        null
      )
    )
  )
)

is your primary key in your view is unique?

Yes I can confirm that

May I Know what was the previous code used for this one  totalCount: length(local!datasubset.data),

you can check the column causing the issue ,and add null conditions for that .It could be that some of the filters are causing the result to be different from what you expect.

 mollyn126  Now your grid working as expected?

Sorry for the delay in response! My grid worked right after changing totalCount to length(...). Originally it was totalCount: local!datasubset.totalCount,
