I am new to AEM6.2. We have requirement to create custom multifield but it is not working, i don't have any service pack installed with AEM6.2 instance.
See this article and video on how to create a component that has a dialog with a multi field - Scott's Digital Community: Creating an AEM 6.2 HTML Template Language component that uses a Multi-Fi...
Hope this helps...
SP1 is needed and hotfix also needed
The sequence is
1. Get fresh AEM6.2 instance
2. Install hotfix
3. Restart CQ instance
4. Install SP1
Please follow above steps to ensure custom multifield working.
From what I am aware of, there is no need of any specific SP's. Guess there might be something wrong with the approach being followed. Also, you can wait for other members to respond on the same.
