[jira] [Resolved] (OLINGO-919) $count is not supported as last segment on Functions/Actions

["Christian Amend (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OLINGO-919?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Christian Amend resolved OLINGO-919.
------------------------------------
    Resolution: Not A Problem
      Assignee: Christian Amend

[~rareddy] this already works as long as the function is composable.
See this example url: /odata-server-tecsvc/odata.svc/FICRTCollESTwoKeyNavParam(ParameterInt16=2)/$count

The default value for "isComposable" is false which means that no further path segments must come after the function call. Not even system query options.
See here in the specification: http://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part3-csdl/odata-v4.0-errata02-os-part3-csdl-complete.html#_Toc406398014

Actions must not be followed by any path segments like $value or $count as stated in the ABNF. You can of course specify $count=true as a uri parameter in the query options part if the returned resource is a collection.  This should already work as well.

> When function (including function imports) and action (and AI ) return collection values, then that url can end with $count. For reference see [1]
