In a Interface I want to show a Paging Grid with multiple columns and multiple r

@clarke. In the sample code, it throws an error.
load(
local!pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: 10,
sort: a!sortInfo(
field: "m_id",
ascending: false
)
),
with(
local!data:rule!sampleTable_db(),
local!datasubset:todatasubset(local!data,local!pagingInfo),
a!gridField(
totalCount: local!datasubset.totalCount,
columns: {
a!gridTextColumn(
label: "ID",
field: "m_id",
data: index(local!datasubset.data, "m_id", null)
),
a!gridTextColumn(
label: "Name",
field: "name",
data: index(local!datasubset.data, "name", null)
),
a!gridTextColumn(
label: "Number",
field: "number",
data: index(local!datasubset.data, "number", null)
)
},
value: local!pagingInfo
)
)
)

Error ("Expression evaluation error at function a!formLayout: Error evaluating function 'todatasubset' : [Ljava.lang.Object; cannot be cast to com.appiancorp.suiteapi.common.paging.DataSubset").
