That's not necessarily true.
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).
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.)
I will think a little about how columns parameters should be expressed,
probably using the macro's content, with a default on standards columns.

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 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 Hi All,
I'm working on designing LiveTable 2.0 macro, an xwiki/2.0 macro that is
supposed to work similar to current LiveTable (say 1.0) Macro. By looking
at
LiveTable 1.0 macro code I encountered few problems that confuses me a
lot.
* First, LiveTable macro is different from other macros (those I have
seen
/
written so far) in which the generated content is "live"... Normally
macros
replaces the macro block with some other generated content but here
LiveTable macro makes use of AJAX to fetch content dynamically. So the
question, is LiveTable a macro or is it something else? Stuffing
JavaScript/AJAX code inside a rendering 2.0 feels unfamiliar to me.
* Second, existing LiveTable macro can be viewed in several ways:
1. Way of presenting a list of documents containing an object of a
specific
class.
2. Way of presenting a list of documents matching a criterion.
3. Generic way of presenting information mactching a criterion.
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).

3) is the same as 2 in the context of XWiki since everything is a document
;-)
Thus you should make the macro aiming at 1) and 2)
-> Either the user specifies an object name and the macro displays documents
holding such an object
-> Or the user specifies a data source document and the macro displays what
the data source tells it to
WDYT?

* Third,
LiveTable macro uses several resources.
1. XWiki.LiveTableResults
2. XWiki.LiveTableResultsMacros
3. LiveTable JavaScript widget & CSS
I would like to for the javascript API to be extended, being able to
listen to more events(not just xwiki:livetable:newrow).
If we decide that LiveTable 2.0 macro should
serve the same purpose as
LiveTable 1.0 macro, should these resources be reused? (within the 2.0
rendering macro)
Please help me to clarify these issues, I'm a bit lost here.
Many thanks.
