Hi,
Executing a query with format=debug and a property of type record where at
least one field has a value e.g.
{{#ask: [[GOslim:membrane;?;?]] | format=debug}}
gives the error
Fatal error: Call to a member function findPropertyTypeID() on a
non-object in
/w/extensions/SemanticMediaWiki/includes/SMW_DataValueFactory.php on line
130
Queries with other format values than 'debug' e.g. 'format=table' are
working ok and give the expected results.
Also {{#ask: [[GOslim:?;?;?]] | format=debug}} (no field values given)
returns the expected result.
It seems the function newDataItemValue is at some point called with the
variable $property having the value '1' causing
if ( !is_null( $property ) ) {
$typeId = $property->findPropertyTypeID();
to throw the error.
Changing the if to if ((is_object($property)) && (!is_null($property)))
results in an empty white page instead of the error message.
I created such a record property on sandbox.semantic-mediawiki.org and see
there the same problem, except that with format=debug I don't get an error
message but always a white empty page.
Versions I use:
MediaWiki 1.18.1
Semantic MediaWiki (Version 1.8 alpha) (r115105)
Cheers,
Gu
