#3701 closed enhancement (fixed)

Allow setting an attribute so content can be displayed when layers don't have query results.

Description

Need to add an attribute to the [resultset ...] tag so that we can display something if a layer doesn't have any results. For example we might output an empty object for JSON output...

Oops, syntax is like so: 

[resultset layer="foo" nodata="layer foo has no results available"]
  [feature]...[/feature]
[/resultset]

Normal operation would be to output with nothing for this block if layer foo had no results (e.g. nodata="").

Fixed in 6.0 and trunk documentation in r12651. Updated template_output with nodata as an attribute to resultset. Also modified the formatting (so the nodata changes will be a bit difficult to find..., sorry).
