| Field | Value |

| Fully Qualified Name | `eo.web.webview.CRW03407SF.CRW03407SF02DBean` |
| Layer | Data Bean / View Component (Controller layer -- X33 framework DataBean) |

## 1. Role

### CRW03407SF02DBean.loadModelData()

`loadModelData` is a **model data routing (dispatch) method** that implements the `X33VDataTypeBeanInterface` contract for the K-Opticom web framework. It serves as a **property-based data accessor** that returns business values for configurable UI form fields by key-subkey lookup. Specifically, it supports three **data item types**: Tab Code (タブコード, the unique identifier for a tab panel), Tab Name (タブ名称, the display label of a tab panel), and Screen ID (画面ID, the internal page identifier). For each item type, it supports three **sub-property accesses**: `value` (the current data value), `enable` (whether the field is enabled for user interaction), and `state` (the component's validation/error state). This method acts as a **delegation layer** between the X33 framework's typed-data-bean infrastructure and the bean's internal fields, enabling the framework to dynamically bind tab metadata to form components without compile-time field references. It is called by the parent screen bean `CRW03407SFBean` during tab-repeat list initialization (itemID `ecr0301b010cbsmsg1list`) to populate per-tab metadata for the "Business-Specific Settings by Organization Tab Overview Meeting Details" screen (業務個別設定組織別タブ一覧照会詳細).

**Block descriptions:**

- **Null Guard (L183):** If either `key` or `subkey` is `null`, the method returns `null` immediately. This prevents `NullPointerException` on subsequent string operations and is the standard null-safety contract for X33 framework data beans.
- **Separator Scan (L187):** `key.indexOf("/")` is computed but **never used** in this method. The variable `separaterPoint` is unused -- likely leftover scaffolding from a future feature that was intended to split a compound key (e.g., `"type/subkey"`).
- **Three Data Item Type Dispatches:** Each top-level branch checks `key` against a Japanese string literal, then dispatches to the appropriate getter based on `subkey` (case-insensitive comparison).

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The **item type identifier** -- a human-readable Japanese string that selects which tab metadata property to resolve. Valid values: `"タブコード"` (Tab Code), `"タブ名称"` (Tab Name), `"画面ID"` (Screen ID). The key determines which of the three metadata groups (tab code, tab name, screen ID) the method will access. |
| 2 | `subkey` | `String` | The **sub-property selector** within the matched item type. Case-insensitive. Valid values: `"value"` (returns the current data value), `"enable"` (returns whether the field is enabled for editing), `"state"` (returns the component validation state string). |

**Internal fields read:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `l1_tab_cd_value` | `String` | Current tab code value (initializes to empty string `""`) |
| `l1_tab_cd_enabled` | `Boolean` | Tab code field enabled/disabled flag (defaults to `false`) |
| `l1_tab_cd_state` | `String` | Tab code field validation/state message (initializes to `""`) |
| `l1_tab_nm_value` | `String` | Current tab name display label (initializes to `""`) |
| `l1_tab_nm_enabled` | `Boolean` | Tab name field enabled/disabled flag (defaults to `false`) |
| `l1_tab_nm_state` | `String` | Tab name field validation/state message (initializes to `""`) |
| `l1_pg_id_value` | `String` | Screen ID value (initializes to `""`) |
| `l1_pg_id_enabled` | `Boolean` | Screen ID field enabled/disabled flag (defaults to `false`) |
| `l1_pg_id_state` | `String` | Screen ID field validation/state message (initializes to `""`) |

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `CRW03407SF02DBean.getL1_pg_id_enabled` | CRW03407SF02DBean | - | Returns `l1_pg_id_enabled` field -- Screen ID enable status |
| R | `CRW03407SF02DBean.getL1_pg_id_state` | CRW03407SF02DBean | - | Returns `l1_pg_id_state` field -- Screen ID validation state |
| R | `CRW03407SF02DBean.getL1_pg_id_value` | CRW03407SF02DBean | - | Returns `l1_pg_id_value` field -- Screen ID data value |
| R | `CRW03407SF02DBean.getL1_tab_cd_enabled` | CRW03407SF02DBean | - | Returns `l1_tab_cd_enabled` field -- Tab code enable status |
| R | `CRW03407SF02DBean.getL1_tab_cd_state` | CRW03407SF02DBean | - | Returns `l1_tab_cd_state` field -- Tab code validation state |
| R | `CRW03407SF02DBean.getL1_tab_cd_value` | CRW03407SF02DBean | - | Returns `l1_tab_cd_value` field -- Tab code data value |
| R | `CRW03407SF02DBean.getL1_tab_nm_enabled` | CRW03407SF02DBean | - | Returns `l1_tab_nm_enabled` field -- Tab name enable status |
| R | `CRW03407SF02DBean.getL1_tab_nm_state` | CRW03407SF02DBean | - | Returns `l1_tab_nm_state` field -- Tab name validation state |
| R | `CRW03407SF02DBean.getL1_tab_nm_value` | CRW03407SF02DBean | - | Returns `l1_tab_nm_value` field -- Tab name data value |

**CRUD Classification:** All 9 method calls are **Read (R)** operations. This method performs **zero writes** (no Create, Update, or Delete). It exclusively delegates to internal getter methods that return fields already populated by earlier processing steps in the screen lifecycle (typically by CBS calls in the parent `CRW03407SFBean`).

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:CRW03407SF | `CRW03407SFBean.addRepeatItem` ("業務個別設定組織別タブ一覧照会詳細") -> `new CRW03407SF02DBean` -> `X33 framework invokes loadModelData` | `getL1_tab_cd_value [R] in-memory field`, `getL1_tab_nm_value [R] in-memory field`, `getL1_pg_id_value [R] in-memory field` |

**Caller context:** The method is instantiated as a **data-repeat child bean** within the parent screen bean `CRW03407SFBean`. The parent creates a `CRW03407SF02DBean` instance and adds it to the `ecr0301b010cbsmsg1list_list` repeat list. The X33 framework then calls `loadModelData` on each instance to populate form field values during screen rendering. There are **no direct programmatic callers** from application code -- access is entirely through the X33 framework's typed-data-bean mechanism.
