Hi André.
I am not an ST expert at all, but I really think there is no support for
generic method invocation on ST expressions: the only methods supported
seem to ne related to properties, à la JavaBean.
For your use case, I'd change a bit the application logic by providing a
C3 REST controller that would act as a data conversion proxy between
the sitemap and the actual REST resource you are currently dealing with.
In this way you could query the external REST resource from the C3 REST
controller body and prepare the data in a format that's suitable for ST.

Andre,
In my opinion, if you are dealing with XML data, you should turn your eyes
into XSL[T] instead of ST.

Is there any reasonable benefit from using ST in transform layer ? I
tend to believe that C2/C3 authors overly favor ST templates in the

deadly simple/fast to compute (transform data) while being very
general-purpose ? Or is there any other reason ? In my opinion ST is
pretty exotic, i mean it is neither any valid standard, nor seen in
any favorable (Java EE) technology stack.
As this case shows, its not a valid engine for general-purpose problems.
Im not giving here the alternatives yet, because i would like to hear
first the reasons behind choosing ST as a preferable template engine
in C2/C3.
AFAIK, ST is not preferred, it's barely the only one available so far
in C3.
And I don't remember ST to be available at all in C2.1 and C2.2.
C2.1 and C.2.2 have instead a wider range of supported template engines,
including JX (my favorite) [1] [2].
If you'd like to port JX (or any other templating engine) to C3, your
contribution is more than welcome.

Re: [C3] Sting template, passing argument to method
I got this problem solved. As the DTO holds the requested information as

With ST it is easy to iterate:
tribc:socials
$statistics.socialEventParticipation: { entry |

tribc:name$entry.key$/tribc:name
tribc:number$entry.value$/tribc:number

I use ST to create the initial XML from a DTO returned by a REST
resource ('EventResource'), like
...
MapString, Object map = new HashMapString, Object();
EventStatisticsDTO dto = eventFacade_.getStatistics(eventId);
map.put(statistics, dto);
return URLResponseBuilder.newInstance(
servlet:tribc-evt:/event-statistics. + format, map
).build();
The tribc-evt:/event-statistics calls upon the sitemap.
Depending on 'format' (either 'xml' or 'json'), I leave the XML as it
is, or I transform the XML to JSON using XSL.

RE: [C3] Sting template, passing argument to method
Lol... you beat me to giving the solution. It's indeed dead simple. And
Franscesco is right about ST only supporting javabeans style access. I had a
similar issue in the past passing javascript objects from flowscript to
jxtemplate generator.
So I ended up extending the native JS Object with some methods like values()
and keys() which are iterable. And of course a Map has the same methods
enabling you to get an enumerable of keys/ values or entries.

[C3] Sting template, passing argument to method

My question is now: How to pass a argument to a given method on an
