[Semediawiki-user] [SRF] undefined method error when creating timeline

[Greg V. <gvargas@MIT.EDU>]

Hello,

I'm trying to create a timeline using SRF, but I'm getting this error:

*Fatal error*: (...) Call to undefined method
SMWPropertyValue::getXSDValue() in *
[...]/extensions/SemanticResultFormats/Timeline/SRF_Timeline.php* on line *
64*

When I take the date out of the query, the timeline successfully renders
(though it's empty).

I'm trying to make a timeline for these events:
http://gvargas.scripts.mit.edu/ha/index.php?title=Category:Event
on this page: http://gvargas.scripts.mit.edu/ha/index.php?title=Timeline
using the 'Year' field.

Can anyone help me shed some light on this issue?

Thanks,
Greg
