From 46755d1eaed7cc9f7d31cc5279028031cd6f8854 Mon Sep 17 00:00:00 2001 From: Roo Code Date: Tue, 17 Jun 2025 18:52:58 +0000 Subject: [PATCH 1/4] Fixes #4794: Fix marketplace blanking after populating - Fixed state management issue in MarketplaceViewStateManager where displayItems was not properly initialized - Improved handling of marketplace items when no filters are active to ensure all items are displayed - Enhanced initial state loading logic to prevent infinite loops and ensure proper state updates - Fixed getState method to fall back to allItems when displayItems is empty The issue was caused by displayItems being set to an empty array when marketplace items were loaded, even when no filters were applied. This caused the marketplace to appear blank after loading completed. --- .../marketplace/MarketplaceView.tsx | 4 ++- .../MarketplaceViewStateManager.ts | 26 ++++++++++++++++--- 2 files changed, 26 insertions(+), 4 deletions(-) diff --git a/webview-ui/src/components/marketplace/MarketplaceView.tsx b/webview-ui/src/components/marketplace/MarketplaceView.tsx index 8d831d8674..85c6292051 100644 --- a/webview-ui/src/components/marketplace/MarketplaceView.tsx +++ b/webview-ui/src/components/marketplace/MarketplaceView.tsx @@ -46,7 +46,9 @@ export function MarketplaceView({ stateManager, onDone }: MarketplaceViewProps) // Listen for state changes to know when initial data arrives const unsubscribe = manager.onStateChange((newState) => { - if (newState.allItems.length > 0 && !hasReceivedInitialState) { + // Mark as received initial state when we get any state update + // This prevents infinite loops and ensures proper state handling + if (!hasReceivedInitialState && (newState.allItems.length > 0 || newState.displayItems !== undefined)) { setHasReceivedInitialState(true) } }) diff --git a/webview-ui/src/components/marketplace/MarketplaceViewStateManager.ts b/webview-ui/src/components/marketplace/MarketplaceViewStateManager.ts index 7f7324f581..44f9355d67 100644 --- a/webview-ui/src/components/marketplace/MarketplaceViewStateManager.ts +++ b/webview-ui/src/components/marketplace/MarketplaceViewStateManager.ts @@ -97,7 +97,8 @@ export class MarketplaceViewStateManager { // Only create new arrays if they exist and have items const allItems = this.state.allItems.length ?
