Sending plain content is not the only option. You can (and should) put
it in a wrapper, either XML or JSON.

XWIKI-4955: Page with empty content leads to "This template does not exist"
message when viewed in plain mode
Revert the trim() removal, which makes all the validation tests fail
Then the wrong template should be fixed instead of putting a hack... generate whitespaces. I still believe that there
is absolutely no reason
A template don't have to generate white spaces and the issue are not
all templates that generated whites spaces, we just need to fix
templates that generate white space before the actual xhtml content
(i.e. before "<?xml..." in htmlheader.vm),
not to use the trim(), since nobody cares if the
whitespace reaches the
The problem is that you only think about full xhtml content, in that
case yes we don't care about triming that content but that's not our
only use case. You could write templates that return some content you
want to get exactly like it was. An example: you need to write a
service in a document to return the exact content of an object or the
content of the document, with this you will be forced to inject
directly your content in the response object and use
$context.setFinished(true) which is a pain. It's a hack because at Utils level we have no idea
what is the
content, safest is to let user decide how he want to use the content
he produced, you can say you don't care as much as you want i still
don't see how we could decide that noone is allowed to take white
space as meaningful content...
If the goal is to protect against UI templates badly written we should
limit this trim() only to xhtml or html MIME types.
And RDF, and SOAP, and all the other XML types. And CSV. It's irrelevant
for JSON. PDF/RTF/XAR/ZIP are unaffected, since they don't use the
parseTemplate logic. The only one that is affected is text/plain.
