🔧 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:

# 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:

# 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
