Detail in a detail

Question

In version 7.8, details do not work correctly in a detail.

Answer

The parent Id is not passed over from detail to a detail, if useRelationship is not specified. If you declare another detail in a detail, specify: "useRelationship": true

"UsrDetail2": {
    "schemaName": "UsrSchema2Detail",
    "entitySchemaName": "UsrDetail2",
    "filter": {
        "detailColumn": "UsrDetail1",
        "masterColumn": "Id"
    },
    "useRelationship": true
}

Another detail's connection column specified in detailColumn, will be populatd with the value from the parent detail (the first detail) page, from the collumn, specified in masterColumn. The column types should match.

Do not forget to set up columns in the second detail. By default, a detail of a detail does not contain any columns.
