Expanding Reporter


This is a reporter which can expand on items returned from another, contained reporter.

This reporter will expand on a list of sub-items in the original report. See the examples for more information.


NameRequiredAvailable InDefault ValueDescription

[default] /key


The key that will be retrieved from each item in the contained report.

  • If it is a list, this reporter will return an Expanded Supplier result for each of the items in that list.
  • If it is a single item, a single Expanded Supplier result will be returned.
  • If it is empty, the result will depend on whether the allowEmpty parameter is  true or  false.

See allowEmpty for details. 



The name to set each expanded item as when accessing it in the report.

May not be item, as this is reserved for the original item being expanded.




If set to false content matching any of the criteria will be returned. Otherwise, the content must match all criteria. 




If set to true, the parent item will still be returned even if the specified key value is empty.

Filtering and Sorting

You can add filter and sort macros into the this macro. The object being sorted on will be the value of the currently expanded item, as opposed to the original item, or the 'expanded' object. Additionally, the original sort order provided by the internal reporter is not changed if two of the 'expanded' values have an equal sort value.

For example, let's say you want to list the 10 most recent comments to pages which are children of the current page, where the commenter is not in the 'employee' group. You would do something like this:

{expanding-reporter:page:all comments|as=comment}

  {date-sort:comment:creation date|order=descending}

{report-column:title=Date}{report-info:expanded:comment>comment:creation date|format=MMM d, yyyy}{report-column}

{report-empty}_No comments available._{report-empty}


Another example is to pull outgoing links of pages which are from external websites only.

{expanding-reporter:content:outgoing links|as=Outlink}
{boolean-filter:link:is external|value=true|required=true}

{report-info:expanded:Outlink>link:is external}

Converting from expand-on

This macro replaces the expand-on macro present prior to Reporting 3.0.0

Below is an example of converting from expand-on  to {expanding-reporter}. It is a simple report which will output the children of the current page who have comments, as well as the the first 50 characters of each comment, in reverse date order.

Using expand-on

  {expand-on:content:all comments|as=comment}
    {date-sort:content:creation date|order=descending}

{report-column:title=Page}{report-info:expanded:item > content:title|link=true}{report-column}
{report-column:title=Comment Summary}{report-info:expanded:comment > content:body > text:first 50|render=wiki}{report-column}


Using expanding-reporter

{expanding-reporter:content:all comments|as=comment}

  {text-sort:comment:page > content:title}
  {date-sort:content:creation date|order=descending}

{report-column:title=Page}{report-info:expanded:item > content:title|link=true}{report-column}
{report-column:title=Comment Summary}{report-info:expanded:comment > content:body > text:first 50|render=wiki}{report-column}


Things to note

  1. expanding-reporter is around the original report, not inside it.
  2. The text-sort was moved into the expanding-reporter. The reason for this is that expanding does its own sorting on the whole result set. In this case, it makes more sense to group comments by the parent page first, then by their creation date. In other places, you may not want to do that.
  3. The 'expanded:item' and 'expanded:comment' keys are exactly the same as before. The expanding-reporter outputs the same structure as expand-on.
