# 🔧 Fix: Chat With Agent Button Not Enabling Chat Controls

## Problem Identified

After implementing per-user agent isolation, the **"💬 Chat with Selected Agent"** button in the builder panel was not enabling the chat textbox and buttons when clicked.

### Root Cause

The `enable_chat_controls_with_agent()` function was still using the **global** `agents_config` dictionary instead of the per-user session storage:

```python
# OLD (Broken after isolation):
def enable_chat_controls_with_agent(agent_name):
    agent_json = agents_config.get(agent_name, "")  # ❌ Global storage
```

Since agents are now stored per-user in the session manager, the global dictionary was empty, causing the function to always return the disabled state.

## Solution Applied

Updated the function to use **per-user agent storage**:

```python
# NEW (Fixed):
def enable_chat_controls_with_agent(agent_name, request: gr.Request):
    """Enable chat controls and show proper agent greeting when agent is selected - per-user isolation."""
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage
```

### Changes Made:

1. **Added `request: gr.Request` parameter** to the function signature
2. **Replaced** `agents_config.get(agent_name, "")` with `get_user_agent(request, agent_name)`
3. **Updated docstring** to indicate per-user isolation

---

## How It Works Now

1. User selects an agent from the dropdown
2. User clicks **"💬 Chat with Selected Agent"**
3. Function retrieves agent from **user's session** (not global)
4. If agent exists:
   - ✅ Displays agent greeting
   - ✅ Enables chat input textbox
   - ✅ Enables send button
   - ✅ Enables reset button
5. User can now chat with their agent!

## Testing

### To Verify Fix:

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. **Verify**:
   - ✅ Chat shows agent greeting message
   - ✅ Text input box is enabled (not greyed out)
   - ✅ Send button is enabled
   - ✅ Reset button is enabled
   - ✅ You can type and send messages

## Related Functions

This was the **last remaining function** that needed updating for per-user isolation. Other functions already fixed:

- ✅ `load_agent_to_builder()` - loads agent for editing
- ✅ `remove_selected_agent()` - removes agent
- ✅ `chat_selected_agent()` - loads agent for chat panel
- ✅ `refresh_chat_dropdown()` - lists user's agents
- ✅ `handle_generate()` - saves new agents
- ✅ `chatpanel_handle()` - handles chat messages
- ✅ **`enable_chat_controls_with_agent()`** - enables chat UI (FIXED)
