Patch for SMW_Subobject.php
Hi,
Empty properties in Subobjects create an error saying that an Attribute value
can't be empty.
This use case can easily occur when declaring subobjects trough Forms/Templates
since you would specify each property, which could end with an empty parameter
value:
{{#subobject:DeliveryAddress| In_Country=United States | In_State= New York}}
{{#subobject:DeliveryAddress| In_Country=Luxembourg | In_State= }}
The source code's comments in SMW_Subobject.php seem to indicate that
properties with empty values were supposed to be correctly ignored, but testing
the number of parameters got after a split on the "=" character is not enought
since there will be 2 elements in the resulting array, the latter being an
empty string.
Quick patch joined.
