I have an issue where a cq:dialog is persisting the information correctly, but when the authoring page loads the information is not populated back into the dialog.
I can troubleshoot issues in my Java code using printlns and the debugger. I can troubleshoot issues in HTL by writing values into the HTML.
But how do I troubleshoot issues with the cq:dialog?
Try upgrading your core components . Make sure the version you're upgrading to is compatible with your AEM version.
Check if there are any errors in the browser console when loading the page
Also, check error.log for any errors
There might be some js errors causing the issue.
