[Users] Geoext - Print Error

[Andreas Hocevar]

Hi Till,

the example you were looking at is from current trunk, and there were some changes since 0.7. You either have to base your code on the example found in the 0.7 release, or use GeoExt trunk. I would suggest the latter, because printing has been improved since 0.7.

Regards,
Andreas.
