Was Unable to repro with 10.1 so the FME 2012 code drop must of fixed this issue.
解决办法
The problem was not the vertical coordinate system. Per Laura at Safe, the problem is trying to create a new Spatial ETL Tool in a new toolbox, before the toolbox is initialized.The workaround is to create the new toolbox, then click on the plus (+) sign next to the name of the toolbox in ArcCatalog, before creating the new Spatial ETL Tool in the toolbox. This initializes the toolbox, and the Spatial ETL Tool can then be created without any errors.From: <a href="mailto:support@safe.com" target="_blank">support@safe.com</a> [mailto:<a href="mailto:support@safe.com" target="_blank">support@safe.com</a>] Sent: Tuesday, September 17, 2013 3:55 PMTo: Margaret MaherSubject: RE: C49570 - #980720 ESRIReprojector transformer fails [ ref:00D3ePES.5003HSeAU:ref ]Hi Margaret, I'm writing to let you know that PR#35034 (NIM075278) has been fixed.
