## 1. Role

### KKW00127SF02DBean.loadModelData()

This method serves as the **central data dispatch and access router** for the Service Contract screen (KKW00127SF). It implements a **key-value lookup pattern** that maps human-readable Japanese field names (the `key` parameter) to the appropriate internal bean properties and their metadata states (the `subkey` parameter). The method handles 11 distinct business data categories: single-value fields such as Service Contract Status, Application Detail Number, Fee Group Code, Service Start Desired Date, Payment Method Succession Flag, Referral Code, Service Code, Update Date Time, and Auto Inquiry Processing Status Code; as well as two list-type fields — Service Contract Status List and Referral Code List — which support both count queries (via `"*"`) and indexed item delegation. For each non-list field, the method branches on the `subkey` to return either the actual data value (`"value"`) or the associated UI state/control flag (`"state"`). For list-type keys, the method parses a separator-delimited index from the key string, supports wildcard `"*"` to return the list size, and delegates to the nested `X33VDataTypeStringBean.loadModelData()` to retrieve the sub-property of a list element. This pattern is the core of the X33 web framework's data binding mechanism, enabling JSF/facelet pages to access bean data through uniform `#{bean.loadModelData('fieldKey', 'subkey')}` EL expressions.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The Japanese-language business field identifier that selects which data category to retrieve. Supported values are: "サービス契約ステータス" (Service Contract Status), "申請明細番号" (Application Detail Number), "サービス契約ステータスリスト" (Service Contract Status List), "料金グループコード" (Fee Group Code), "サービス開始希望日" (Service Start Desired Date), "支払方法引継フラグ" (Payment Method Succession Flag), "紹介コードリスト" (Referral Code List), "紹介コード" (Referral Code), "サービスコード" (Service Code), "更新年月日時刻（サービス契約）" (Update Date Time for Service Contract), "自動照会処理状態コード" (Auto Inquiry Processing Status Code). For list-type keys, the key may contain a separator "/" followed by a `"*"` wildcard or a numeric index. |
| 2 | `subkey` | `String` | The access mode specifier. For single-value fields, `"value"` returns the actual data content and `"state"` returns the associated UI state/control flag. For list-type fields, this is forwarded to the nested element's `loadModelData()` to select a sub-property of the list item. |

**Instance fields read:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `svc_kei_stat_lis_list` | `X33VDataTypeList` | Service Contract Status List - managed list of status sub-items |
| `intr_cd_list_list` | `X33VDataTypeList` | Referral Code List - managed list of referral code sub-items |

All operations are **Read (R)** - this method does not perform any Create, Update, or Delete. It is purely a data accessor that routes lookups to internal bean property getters. List-type fields access `X33VDataTypeList` instances (`svc_kei_stat_lis_list`, `intr_cd_list_list`) which are initialized as `ArrayList<X33VDataTypeStringBean>` containers in the constructor.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Bean: KKW00127SF02DBean | `KKW00127SF02DBean.loadModelData(key, subkey)` | `getSvc_kei_stat_value [R] svc_kei_stat_value` |

**Callers analysis:** This method's only direct caller from the code graph is itself - a self-referential call within the same bean class. This occurs in the list-type handling (Block 4 and Block 8) where list elements are `X33VDataTypeStringBean` instances that also implement `loadModelData()`, enabling recursive nested property access. The method is invoked from JSF/facelet EL expressions on the KKW00127SF screen by UI bindings that pass the Japanese field name and `"value"` or `"state"` as subkey, or `"ListName/index"` as key for list items.

## 6. Per-Branch Detail Blocks

**Block 1** - [IF] `(null check: key == null || subkey == null)` (L366)

| 2 | RETURN | `return getSvc_kei_stat_value();` - returns the service contract status data [-> L373] |
