# BC Setup Wizard Generator

Automates creation of assisted setup wizards for Business Central setup tables following Guided Experience patterns.

## Overview

Generates complete NavigatePage setup wizards with step-based navigation, banner images, temporary records, and Guided Experience registration. Follows Microsoft patterns for assisted setup.

**Complete code templates available in**: [references/code-templates.md](references/code-templates.md)

## Prerequisites

- AL workspace with setup table
- Setup table with fields to configure
- (Optional) Setup page for post-wizard access

## Workflow

### Step 1: Gather Information

Collect from user:
- Setup entity name (e.g., "Statistical Account")
- Setup table name and ID
- Prefix (e.g., "BCS")
- Number of configuration steps (typically 2-4)
- Field groups per step
- Documentation URLs (video + written)

### Step 2: Plan Wizard Steps

Define wizard structure:
- **Step 1**: Welcome - InstructionalText explaining wizard purpose
- **Step 2-N**: Configuration - Field groups by logical category
- **Final Step**: Review & Finish - Read-only summary of all settings

Example 3-step wizard:
1. Welcome
2. Attachments Settings (Step 1/2)
3. Number Series Setup (Step 2/2)
4. Review & Finish

### Step 3: Create Wizard Page

Create NavigatePage with:
- `PageType = NavigatePage`
- `SourceTable = [Setup Table]`
- `SourceTableTemporary = true` ← Critical for unsaved workflow

Location: `src/Page/[Prefix][Entity]SetupWizard.Page.al`

See [code-templates.md](references/code-templates.md#wizard-page-structure) for complete structure.

### Step 4: Add Banner Groups

Add two banner groups at top of layout:
- **SetupWIPBanner**: Visible during configuration steps
- **SetupFinishedBanner**: Visible on review/finish step

Uses Media Repository records:
- `AssistedSetup-NoText-400px.png` (WIP)
- `AssistedSetupDone-NoText-400px.png` (Finished)

See [code-templates.md](references/code-templates.md#banner-groups) for complete code.

### Step 5: Add Step Groups

Create one group per step with:
- `Visible` property bound to `StepXVisible` boolean
- InstructionalText for welcome/review steps
- Field groups for configuration

**Critical**: Use step counters in captions for user guidance:
- `Caption = 'Attachments Settings 📎(Step 1/3)'`

See [code-templates.md](references/code-templates.md#step-groups) for complete patterns.

### Step 6: Add Navigation Actions

Add three actions in `area(Processing)`:
- **ActionBack**: `Enabled = BackActionEnabled`, calls `NextStep(true)`
- **ActionNext**: `Enabled = NextActionEnabled`, calls `NextStep(false)`
- **ActionFinish**: `Enabled = FinishActionEnabled`, calls `FinishAction()`

All have `InFooterBar = true` for bottom positioning.

See [code-templates.md](references/code-templates.md#navigation-actions) for complete code.

### Step 7: Add Page Triggers

**OnOpenPage**:
- Initialize temporary record from actual setup table
- Call `EnableControls()` to show first step
- Call `LoadSetupBanner()` to load banner images

**OnQueryClosePage**:
- If `FinishedProcess = true`: Commit changes, mark setup complete
- Else: Confirm user wants to exit without saving

See [code-templates.md](references/code-templates.md#page-triggers) for complete implementation.

### Step 8: Add Navigation Procedures

Create local procedures:

**ResetControls()**: Reset all visibility booleans and action states

**NextStep(Backwards: Boolean)**: Increment/decrement Step option, call EnableControls()

**EnableControls()**: Case statement routing Step to SetControlsStepXX()

**SetControlsStepXX()**: Set visibility for specific step, enable/disable actions

See [code-templates.md](references/code-templates.md#navigation-procedures) for complete code.

### Step 9: Add Data Management Procedures

**InitRecord()**: 
- Check if setup record exists
- Create temporary record from existing or initialize new

**CommitRecord()**:
- Transfer temporary record to actual setup table
- Insert if new, Modify if exists

**FinishAction()**:
- Set `FinishedProcess = true`
- Close page (triggers OnQueryClosePage commit)

See [code-templates.md](references/code-templates.md#data-management-procedures) for complete code.

### Step 10: Add Setup Banner Loading

**LoadSetupBanner()**:
- Get Media Repository records by name
- Get Media Resources by reference
- Set `BannersVisible` if media has value

See [code-templates.md](references/code-templates.md#banner-loading-procedure) for complete code.

### Step 11: Declare Variables

Declare variables:
- Record variables: Setup table, Media Repository (2), Media Resources (2)
- Codeunit: `GuidedExperience`
- Boolean: StepXVisible (per step), BackActionEnabled, NextActionEnabled, FinishActionEnabled, FinishedProcess, BannersVisible
- Option: `Step` with values matching step groups

See [code-templates.md](references/code-templates.md#variable-declarations) for complete list.

### Step 12: Create Registration Codeunit

Create codeunit with event subscriber:
- Subscribe to `Codeunit::"Guided Experience"::OnRegisterAssistedSetup`
- Call `AssistedSetup.InsertAssistedSetup()` with:
  - Title and description labels
  - Time estimate (minutes)
  - Wizard page ID
  - Assisted Setup Group
  - Video URL and category
  - Documentation URL

Location: `src/Codeunit/[Prefix][Entity]SetupManagement.Codeunit.al`

See [code-templates.md](references/code-templates.md#registration-codeunit) for complete code.

### Step 13: Build and Test

1. Build project: `al_build`
2. Publish: `al_publish`
3. Test from:
   - Assisted Setup page (search "Assisted Setup")
   - Extension Management (Setup actions)
4. Verify:
   - Navigation works (Back/Next/Finish)
   - Banners display correctly
   - Exit confirmation on close without finish
   - Changes saved on finish
   - Completion check marked

## Troubleshooting

### Wizard doesn't appear in Assisted Setup
**Cause**: Event subscriber not firing or registration failed  
**Fix**: Check `OnRegisterAssistedSetup` event subscriber syntax, verify codeunit compiles without errors

### Banners don't display
**Cause**: Media Repository records not found or media reference empty  
**Fix**: Check exact image names (`AssistedSetup-NoText-400px.png`, `AssistedSetupDone-NoText-400px.png`), verify Media Repository exists in base BC

### Changes saved even when clicking X to close
**Cause**: `OnQueryClosePage` not checking `FinishedProcess` flag  
**Fix**: Ensure `if FinishedProcess then` condition exists, verify FinishAction sets flag before CurrPage.Close()

### Steps don't navigate forward/backward
**Cause**: Step option enum values don't match group names, or EnableControls case statement incomplete  
**Fix**: Verify Step option has value for each step (Step10, Step20, Step30, etc.), check Case statement includes all values

### Error on finish: "Record already exists"
**Cause**: CommitRecord trying to Insert when record exists  
**Fix**: Check `if not SetupRecord.Get() then Insert else Modify` pattern in CommitRecord procedure

### Setup marked complete but changes not saved
**Cause**: CommitRecord not called before CompleteAssistedSetup  
**Fix**: Ensure OnQueryClosePage calls CommitRecord() before GuidedExperience.CompleteAssistedSetup()

### Review step shows editable fields
**Cause**: Review step groups missing `Editable = false` property  
**Fix**: Add `Editable = false` to all field groups in final review step

## Quick Reference

**Snippet**: Use Waldo's `tpagewizard3stepswaldo` snippet for rapid scaffolding

**Core Pattern**: Temporary record → User edits → Finish commits → Mark complete

**Key Properties**:
- Page: `PageType = NavigatePage`, `SourceTableTemporary = true`
- Actions: `InFooterBar = true`
- Groups: `Visible = StepXVisible`

**Required Codeunits**: Guided Experience (InsertAssistedSetup, CompleteAssistedSetup)
