Because if we do that we break all code using $object.fieldName to

i said in a previous mail when Thomas raised the issue, i would prefer
that $object.fieldName does not call display but whatever the change
you make to the API it will break it for users.
Hi devs,
For 2.0 syntax we make XWikiDocument.display() enclose the result in
{{html}}{{/html}} since it's supposed to generate html and that we
should not have to use {{html}}{{/html}} in the syntax when we call
$doc.display("somefield").
Now the issue is that public api Object and Document get() methods
does not return the value but call display. But users (and us) used to
access string value using $object.somefield instead of
$object.getProperty("somefield").getValue() which is the correct form
to access an object field value.
I feel that
$object.fieldName is way more natural as
$object.getProperty("somefield").getValue()
than as
$object.display().
Otherwise put, why can't we change getters to return
$object.getProperty("somefield").getValue()?
Because of this wrong use of display() we have a big change in the api
form user point so the question is what do we do ?
I can see the following solution:
1) it's not a real change in the API, user should use the right way.
It's ok like that.
2) we "optimize" XWikiDocument.display() by generating
{{html}}{{/html}} only when it's necessary (if the result really is
html)
2.a) if it contains "<" or ">"
2.b) when it's not a BaseStringProperty/NumberProperty/DateProperty
since theses properties does not really need to produce HTML
3) we clean the display result in Object/Document.get by removing the
{{html}}{{/html}} when the result does not really contains html (more
or less the same way to find it than 2))
WDYT ?
I'm +1 for 2.a) (I don't like b, i think the generic way is better)
since i don't think we can "change" the API even if it's not a real
change and this solution is not that much a hack, it makes display()
return cleaner anyway.
3) as the advantage of fixing only the problematic API but it's really
too crappy IMO
