 # Session Log
 
+## Session: 2025-03-17
+
+### Overview
+Fixed bugs in the UI progress callback mechanism for report generation.
+
+### Key Activities
+1. Identified and fixed an AttributeError in the report generation progress callback:
+   - Diagnosed the issue: 'Textbox' object has no attribute 'update'
+   - Fixed by replacing `update(value=...)` method calls with direct value assignment (`component.value = ...`)
+   - Committed changes with message "Fix AttributeError in report progress callback by using direct value assignment instead of update method"
+   - Updated memory bank documentation with the fix details
+
+2. Enhanced the progress indicator to ensure UI updates during async operations:
+   - Identified that the progress indicator wasn't updating in real-time despite fixing the AttributeError
+   - Implemented a solution using Gradio's built-in progress tracking mechanism
+   - Added `progress(current_progress, desc=status_message)` to leverage Gradio's internal update mechanisms
+   - Maintained direct value assignments to custom UI elements for redundancy
+   - Tested the solution to confirm progress indicators now update properly during report generation
+
+### Insights
+- Gradio Textbox and Slider components use direct value assignment for updates rather than an update method
+- Asynchronous operations in Gradio require special handling to ensure UI elements update in real-time
+- Using Gradio's built-in progress tracking mechanism is more effective than manual UI updates for async tasks
+- The progress callback mechanism is critical for providing user feedback during long-running report generation tasks
+- Proper error handling in UI callbacks is essential for a smooth user experience
