Parsys not showing up for the custom components occasionally in edit mode of AEM React page

[vs5]

Hi,

We see some issue of parsys not showing up for the custom components frequently, when the page refresh or switch the mode (edit to preview, back to edit) parsys is showing. 

Application is on Adobe CS. Appreciate, any suggestions.

Hi @vs5 ,

Can you check if you see any error in browser console.
Also please check the below link and see if you are missing something. The below link  tries to create a column control with a parsys in it. You can extend the same implementation.

Hope it helps!

The issue of the parsys not showing up intermittently for custom components in AEM React pages could be due to a variety of factors. Here are some potential solutions to address this issue:

1. Component Initialization:
   Ensure that the custom components are properly initialized in the React app. Sometimes the parsys may not render properly if the React components aren't fully loaded or initialized when switching between modes (edit to preview). Verify that your components have the necessary lifecycle methods to ensure they render correctly in AEM's edit and preview modes.

2. AEM Dispatcher Cache:
   The dispatcher cache might be causing issues with refreshing the content in edit mode. Clear the AEM dispatcher cache and try again, as stale cached content can prevent proper rendering of parsys.

3. React & AEM Integration:
   Ensure that the integration between AEM and React is correctly set up. Check if the React component is being properly embedded within AEM's parsys and that the right component model is being passed to it. Any issues here might cause the component to not show up consistently.

4. Mode Switching Issues:
   The issue might be related to how AEM switches between edit and preview modes. When switching modes, AEM might not be refreshing the DOM properly. Check if there are any JavaScript errors or conflicts when switching modes and make sure that AEM’s editor has fully loaded the page before the switch.

5. Custom Component Logic:
   Look into your custom component's logic. If there are any asynchronous operations (like data fetching), make sure these are handled correctly, as delays might cause issues in the rendering.

6. Client-Side Rendering Conflicts:
   If using client-side rendering for the React application, ensure that the AEM Editor and React app aren’t conflicting. Make sure that the React app is aware of the AEM editing environment, and vice versa.

Summary:

To fix the issue, check initialization, clear the dispatcher cache, verify React-AEM integration, and ensure mode switching works without JavaScript errors. If necessary, debug the page load sequence and component rendering lifecycle.
