[xwiki-users] Panels backward compatibility

I'm resending this mail by using the right subject pattern. Hello, I am trying to upgrade an old XEM to 3.5.1. In this XEM there are some custom panels which have been converted to 2.0 syntax and contain code like this: {{velocity}} {{html}} #panelheader("...") ... #panelfooter() {{/html}} {{/velocity}} Because since 2.7.2 panel macros were converted to 2.0 syntax, because panel macros from inside macros.vm were modified by calling {{html}} wiki macro and because we can't use nested {{html}} macros without wiki="true" parameter, I don't know how to fix this issue besides modifying panel code. This XEM has more than 70 wikis and this I can't just modify all custom (converted to 2.0 syntax) panels manually. Is there a nice solution to this problem ? Should I open an issue on Jira ? Raluca.
