Only draw a simple rectangle box then either move to different location or edit the vertices to change the size. Other draw tools got the same error message too. Thanks.
I use version 3.4 on 7/25/2013, and both WKID on my config.xml & eDrawWidget.xml (<spatialref>102696</spatialref>) are the same. I change this EPSG_GEOGRAPHIC to same as WKID and it works!
