that's what you meant, agreed we don't really need it even in future
versions.

The default JSON source supports tables without objects, and right now
supports certain filters (like document's space or the fact the
document
is orphaned or not). This is how are built the AllDocs, SpaceIndex and
OrphanedPages UIs in XE.
For me the 2.0 syntax livetable should be user-oriented, not
developer-oriented as the velocity one is, and doesn't need to support
custom JSON source (at least not in a first version). Hi Asiri,
Here is some feedback about the live table since I have been using
it on
client projects:
+ things work well with the standard version
- I was a pain when I had to add a custom column with information
from
the documents in the live table
- performance when filtering a lot of documents

I would like the main purpose of the live table to be the display
of a
list of documents from the wiki.
It should be up to the user what documents the live table displays
(with
objects - 1, a query result -2).

I agree with
Oana on this one. The Livetable can be used to suit
any of the
purposes you stated. However if we want to keep the macro as simple
as
possible we could use it only for purposes 1 & 2 and tell
developers to use
the underlying code when trying to achieve 3 since it most cases
that's what
they"ll end up doing when they want to add custom rows, data
sources etc...
1) is the most useful when it comes to writing basic applications -
it
would allow an application writer to
easily create a dynamic list
of the
items of any given class. I think it's the most important for
"basic" users
of this macro
2) is how the livetable is used on more ambitious applications,
requiring a
custom data source to be written -> it's used by "advanced" users
of the
livetable
So the doclist in your example (which I'd call {{documents}} instead
but that's another discussion ;)) would for me use a more generic
version so that we can write other specific macros extending that
generic version instead of rewriting the new one and duplicating lots
of code.
I'd also like to see the ability to use the generic version from the
onset even though it wouldn't be used normally by end users (they'd
use the specialized version).
Then we should have specialized macros for all the needs we already
have in XE.
Here how I see it :
{{doclist /}} // displays all documents on the wiki with no
restriction
{{doclist creator="XWiki.JohnDoe"/}} //displays all docs created by
John Doe
{{doclist class="Blog.BlogPostClass" /}} displays all docs
containing a
Blog Post
{{doclist class="XWiki.SchedulerJobClass" space="Scheduler" /}}
displays
all docs containing a scheduler job in the Scheduler space
I think most of the metadata carried by XWikiDocument should be
supported by the table (dates, author/creator, tags, etc.)
Sounds good. Need support for queries too (query="xwql:...",
query="hql:...." or query="..." and queryType="hql | xwql"
which I
prefer) and the specific params would get transformed into that query.
I will think a little about how columns
parameters should be
expressed,
probably using the macro's content, with a default on standards
columns.
It could even be a nested macro so that you don't have parsing to do.
Thanks
