I keep getting a `Error writing graphviz file to disk.` message when using the
SMW/Semantic Result Formats graph format with the GraphViz extension. Looking
in the error log I see this:
PHP Notice: Undefined index: graphname in
[...]/w/extensions/SemanticResultFormats/formats/graphviz/SRF_Graph.php on line
76, referer: [...]
PHP Notice: Undefined variable: storagename in
[...]/w/extensions/GraphViz/GraphViz.php on line 342, referer: [...]
PHP Warning: fopen([...]/w/images/graphviz/): failed to open stream: Is a
directory in [...]/w/extensions/GraphViz/GraphViz.php on line 360, referer: ...
I use:
Graphviz 0.9.1 alpha (Version r115794)
MediaWiki 1.24alpha (85d4e39)
PHP 5.3.3 (apache2handler)
Semantic Result Formats 1.9
Drawing graphs with the <graphviz> tag works fine.
