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 ?

Idea 1:
======

Add a new #panelheaderold macro in macros.vm and replace all calls of
#panelheader to #panelheaderold in your panels (easy to do with a XWQL
query and 3 lines of scripts).

Slowy migrate panels to new syntax.

Note:
=====

Actually in the future we need to add a new {{panel}} macro, something
like:

{{panel style=".." title="…"}}
… content here …
{{/panel}}

Idea 2:
======

Create a custom Panel wiki macro (give it a name other than "panel"!),
search for:
{{velocity}}{{html}}#panelheader….#panelfooter{{/html}}{{/velocity}} (use
a regex)

Replace with your panel macro.

Should I open an issue on Jira ?

Nope

So this means that none of the macros in macros.vm are API?
Which means that there is no API to make a panel header consistent with the 
panel headers of the default panels?

Good point. Macros in macros.vm are supposed to be APIs and it means we broke 
the backward compatibility at some point in the past (2.7 as suggested by 
Raluca).

We should probably have introduced new macros instead when we introduced the 
conversion to 2.0 syntax.

Now since this is very old we need to decide what we want to do at this point.

Thanks,
Anca

So there is no other way to fix this issue but by modifying the code inside
panels.
Thank you, Vincent.

Raluca.

Thanks
