Re: [Semediawiki-user] Accessing a field on a page holding multiple template instances

[trueskew <tru...@gm...>]

I'm not using SIOs, though I just read about them and I might be able to use
them in other places.

Nice trick with the #show, that looks like it will work for me.   

Thanks again Bob.

Are you using SIOs?  If you are, and are sure that the dates can only be
added in order, you can query to get all the SIOs belonging to a given page
and sort by the date property.

If the dates aren't necessarily in order, you might be able to use a counter
variable (Variables extension + ParserFunctions) on the page, increment it
in every template call, and assign its value as an SIO property ("has index
number"), and then sort on that when you query for SIOs.

Without SIOs, and if the dates are always in order, you could try the
printout options described here http://semantic-mediawiki.org/wiki/SMW_1.5.0

{{#show: {{PAGENAME}}
|?has date
|+order=desc
|+limit=1
}}

should work!
