After I join an SDE feature class to another table in the same SDE, I can create features but can't edit any attributes in the feature class (all greyed out in attribute window). As soon as i release the join everything back to normal. ArcSDE Version 9.3 ArcSDE Server Build for Oracle10g Build 546 Thu Sep 18 12:35:50 2008, Arcgis 10.0 SP2 desktop and ArcInfo level licence. Is this a bug? or is there a setting I can't find??
