Description: The title attribute doesn't always work well with {{PAGENAME}} or {{#var: foo}}

Problem

This should return the author of the current Page, but doesn't work. No Feedback whatsoever: 

<dpl>
 title={{PAGENAME}}
 skipthispage=no
 addauthor = true
 mode=userformat
 format=,,%USER%,
 noresultsheader=¶No result
 redirects=include
</dpl>

It seems that no Magic word or Parserfunction works in this case, however I have not tested them all.

Live Textcase:

Extension:DynamicPageList (DPL), version 3.2.1: Warning: Skipping bad option 'Issue:Title-attribut sometimes doesn't work with magic words like PAGENAME' for parameter 'title'.


Extension:DynamicPageList (DPL), version 3.2.1: Error: No selection criteria found! You must use at least one of the following parameters: category, namespace, titlematch, linksto, uses, createdby, modifiedby, lastmodifiedby, or their 'not' variants


Extension:DynamicPageList (DPL), version 3.2.1: Warning: No results.

Note: DPL 1.9.0 seems to miss a selection criteria. I thougt title= would do it. However, titlematch wont work either.

However THIS works: (returning number of Page Impressions on the Site) 

{{#dpl:
| title = {{{1|{{FULLPAGENAME}}}}}
| addpagecounter = true
| format = ,%COUNT%,,
| skipthispage = no
| noresultsheader=¶No result
}}

Live: %COUNT%

Work around

if you replace 

title={{FULLPAGENAME}}

with 

titlematch={{PAGENAME}}
namespace={{NAMESPACE}}

it works as expected.

This is not a problem of DPL.

Mediawiki does not expand macros like PAGENAME within TAG-delimited user functions. Therefore DPL cannot "see" the page name and consequently it returns the error "NO SELECTION CRITERIA FOUND".

If you use a parser function call instead of the TAG function everything works fine. BUT, pay attention:

The title command expects a fully qualified title. As the current page is NOT residing in the main namespace one needs to use FULLPAGENAME (this will add the namespace prefix).

So, 

{{#dpl: title={{FULLPAGENAME}} | skipthispage=no | addauthor = true | format=,,%USER%, | redirects=include }}

correctly delivers: Trias
