Object cannot be cast from DBNull to other types - OSM Attribute Selector

Oct 30, 2012 at 4:31 PM


weird problem - I'm getting "Object cannot be cast from DBNull to other types" while using the OSM Attribute Selector.

Step by step:

Download OSM Data from the Overpass API (the xapi compatible one) -> pass

Symbolize OSM Data -> pass

OSM Attribute Selector - selecting  Highways (lines) and name attribute -> fail (no difference if File DB or SQL)

Which is unexpected because it had worked a while ago (but I've used an extract from cloudmade but that was too large an therefore extremely slow)

Help appreciated.

Thanks and Regards,

Yes, that's a bug -- it'll be fixed in the next update.
