I tried Visual diff feature in an OOTB instance for geometrixx demo pages and it's working fine but its not working for my website components that are built using sightly instead of JSP.
I am looking for a solution as what needs to be set on the website sightly component in order for it to display difference between versions in both Classic UI and Touch UI
Along with this I would like to know whether AEM 6.2 supports Visual version Diff feature for sightly built components or not. If it doesn't support then does AEM 6.3 includes this fix and resolve the problem?
We are also looking at this functionality since we started using AEM 6.1; it just didn't work!!! Now we are trying to use it in AEM 6.3 and it has lots of issues and the functionality is not stable. You can access the version compare ( compare an old version with the current page copy) functionality from touch UI console: select a page, expand the timeline from left rail and select a version, then it will allow you to compare that version with the latest editing copy. This feature is important and very useful for page review and approval process. This is what we found:
Functionality is not stable, sometime it highlights the diff when sometime it doesn't highlight at all for the whole page.
Most of time, it highlights the difference for some part of the component but not for some text, e.g. paragraph title
It seems take a long long time to load the previous version copy
We are not sure it is a configuration problem or there are some specific requirement on creating a custom component for this to work ( we use sightly for all our components). I also wonder how many customers are using this feature and having the problem; I know for AEM 6.1, we talked with Adobe PS, they even said there were some issues with it.
