# 🔧 Fix: Agent Chat Send Button Now Works

## Problem Identified

After clicking "Chat with Selected Agent", the chat textbox enabled correctly, but when sending a message, users received the error:

```
⚠️ No agent configuration found. Please Generate or Load an agent first.
```

### Root Cause

**Three more functions** were still using the **global** `agents_config` dictionary instead of per-user session storage:

1. `builderpanel_handle_with_dynamic_vars()` - Handles messages in builder panel
2. `chatpanel_handle_with_dynamic_vars()` - Handles messages in deployed chat panel  
3. `update_dynamic_vars_visibility()` - Shows/hides dynamic fields based on agent skills

```python
# OLD (Broken after isolation):
def builderpanel_handle_with_dynamic_vars(agent_name, user_text, histories, ...):
    agent_json = agents_config.get(agent_name)  # ❌ Global storage - returns None
```

Since agents are now stored per-user, the global dictionary was empty, causing `agent_json` to be `None`, which triggered the "No agent configuration found" error in the chat orchestrator.

## Solution Applied

Updated **all three functions** to use **per-user agent storage**:

### 1. `builderpanel_handle_with_dynamic_vars` (Builder Panel Chat)

```python
# NEW (Fixed):
def builderpanel_handle_with_dynamic_vars(
    agent_name, user_text, histories,
    ...,
    request: gr.Request  # ✅ Added
):
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage
```

**Changes:**
- Added `request: gr.Request` parameter
- Replaced 2 instances: `agents_config.get(agent_name)` → `get_user_agent(request, agent_name)`

### 2. `chatpanel_handle_with_dynamic_vars` (Deployed Chat Panel)

```python
# NEW (Fixed):
def chatpanel_handle_with_dynamic_vars(
    agent_name, user_text, histories,
    ...,
    request: gr.Request  # ✅ Added
):
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage
```

**Changes:**
- Added `request: gr.Request` parameter
- Replaced 2 instances: `agents_config.get(agent_name)` → `get_user_agent(request, agent_name)`

### 3. `update_dynamic_vars_visibility` (Dynamic Fields)

```python
# NEW (Fixed):
def update_dynamic_vars_visibility(agent_name, request: gr.Request):
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage
```

**Changes:**
- Added `request: gr.Request` parameter
- Replaced: `agents_config.get(agent_name)` → `get_user_agent(request, agent_name)`

### 4. Agent Picker Dropdown Initial State

```python
# OLD:
agent_picker = gr.Dropdown(
    choices=list(agents_config.keys()),  # ❌ Global storage
)

# NEW:
agent_picker = gr.Dropdown(
    choices=[],  # ✅ Empty, populated per-user by refresh_chat_dropdown
)
```

## How It Works Now

### Builder Panel Chat:
1. User generates/selects an agent
2. User clicks **"💬 Chat with Selected Agent"**
3. Chat controls enable with greeting
4. User types a message and clicks **Send**
5. ✅ `builderpanel_handle_with_dynamic_vars` retrieves agent from **user's session**
6. ✅ Agent processes the message successfully
7. ✅ Response appears in chat

### Deployed Chat Panel:
1. User goes to **"Chat With the Agents You Deployed"**
2. User selects an agent from dropdown
3. User types a message and clicks **Send**
4. ✅ `chatpanel_handle_with_dynamic_vars` retrieves agent from **user's session**
5. ✅ Agent processes the message successfully
6. ✅ Response appears in chat

## Testing

### Quick Test (Builder Panel):

1. **Login** to the app
2. **Build an agent** in the Agent Builder
3. **Select your agent** from the dropdown
4. **Click "💬 Chat with Selected Agent"**
5. **Type a message** (e.g., "What antibiotics do you recommend for pneumonia?")
6. **Click Send**
7. **Verify**:
   - ✅ No error message
   - ✅ Agent responds with relevant information
   - ✅ Conversation continues normally

### Quick Test (Deployed Chat Panel):

2. **User B** builds "AgentB" and chats
3. **Verify**:
   - ✅ Each user chats with their own agent
   - ✅ Responses are agent-specific
   - ✅ No cross-contamination
