Hello,
I have an additionnal remark on this.
Passing "tag=mytag" in the "extraParams" to the livetable macro works
well,
ie the livetable then displays items having passed tag(s).
But I see some limitations, mainly due to the fact that this specific
"extraParam" param "tag" is not linked with the "tagCloud"
parameter of the
livetable macro:
- you don't see, if tagCloud is displayed, what tag(s) was(were) used for
filtering it by default. Tag cloud is displayed as if no tags were selected.
- in that case you might want to really "restrict" that specific livetable
to showing that specific tag(s), and forbid users changing it (but still
display it), but you can't display a "read-only" tag cloud. In fact
it's
worse, as ideally, I think we should restrict the list of tags
displayed/selectable in the tag cloud, to the list of tags provided in
"extraParam" + list of tags "dependent" on any tag of the first list.
BR,
Jeremie

Hi Everyone,
I am new to Xwiki and I am stuck with a little problem and I was
wondering
if any of you lovely people could help?
What I am trying to do is generate a Livetable similar to the documents
macro but only showing a group of selected tags.
Is this possible? and if so how would I go about
doing this?
Sure. You can use the "extraParams" live table parameter (see
http://extensions.xwiki.org/xwiki/bin/view/Extension/Livetable+Macro#HAllac…
) to filter documents by tags. It's very easy to extend the documents
macro to add a new "tags" parameter and pass its value to the
"extraParams". Here's what I did:
(1) I edited XWiki.DocumentsMacro page with the objects editor and I
added a new optional "tags" parameter (a comma-separated list of tags)
(2) From the objects editor, I added this to the macro content, before
the "$!extraParams" != "" test:
#if ("$!xcontext.macro.params.tags" != "")
#set ($tags = $!xcontext.macro.params.tags.split('\s*,\s*'))
#foreach ($tag in $tags)
#set ($extraParams = "${extraParams}&tag=$escapetool.url($tag)")
#end
#end
To better understand this you should read
http://platform.xwiki.org/xwiki/bin/view/DevGuide/WikiMacroTutorial .
Hope this helps,
Marius
Thanks
