I'm using the latest SQL Developer, 3.2.20.09, but it's been occurring under earlier versions too, starting w/ 3.1.
I'm getting hundreds of these errors to the logging Page when I access SQL Server databases and roll my cursor over the database objects. I'm also seeing some with the same key error but 'SCHEMA_NAME' on there too. Any idea what is causing this, and how to fix it? Seems like it might be a bug.
Perhaps your installation went awry or got corrupted somehow? If you cannot find the following in your install directory, then that may be it:
2. Browse the jar file, looking for SQLServerNavigatorResource.properties (if non-English locale, filename may have a locale suffix).
3. Browse that properties file for lines containing the ORACLE_CONNECTION_ICON and SCHEMA_NAME keys.
I was able to find both of these files in the oracle.sqldeveloper.jar file. So it seems that much is correct. Also, I do not suspect a corruption, because this started happening over the past few upgrades that I've done - and each time I replace the entire install with the latest download.
