Hello,

my installation:
MediaWiki 	1.18.1
Semantic Bundle (Version 20120124)
Semantic MediaWiki (Version 1.7.0.2)
Semantic Result Formats (Version 1.7)
Graphviz (Version 0.9.1 alpha)
and some other extensions.

I adopted the examples from: 
http://km.aifb.kit.edu/projects/process/index.php/Main_Page

But I get the following error message (/var/log/apache2/error.log) while processing the process pages. This pages do not load at all (white screen):

PHP Fatal error:  Call to undefined method SMWDIWikiPage::getTypeID() 
in /var/www/mediawiki-1.18.1/extensions/SemanticResultFormats/GraphViz/SRF_Process.php on line 155, referer: http://wiki/wiki/index.php?title=QM:Prozess_Test&action=edit

The process step pages and the rest of my MediaWiki work without 
problems.
I have pages with hand made Graphviz diagrams working.

I tested in Main namespace, too. Same result.

The query behind the template:
{{#ask: [[Category:Prozessschritte]] [[Category:{{FULLPAGENAME}}]]
| ?has OrSuccessor=hasorsuccessor
| ?has Successor=hassuccessor
| ?has ConTrueSuccessor=hascontruesuccessor
| ?has ConFalseSuccessor =hasconfalsesuccessor
| ?has Condition=hascondition
| ?has Role=hasrole
| ?uses Resource=usesresource
| ?has Status=hasstatus
| format=process
| graphsize=12,12
| graphvalidation={{{graphvalidation}}}
| showroles={{{showroles}}}
| showresources={{{showresources}}}
| showstatus={{{showstatus}}}
| showdiscussion=yes
| clustercolor=lightgrey
}}

Do you have any idea, what can cause this error.

Best regards
Mario
