I was finally able to get the dynamic Oracle service object to install and was able to create a smart Object based on one of the tables in the Oracle database. But now when I try to test the Smartobject I am receiving the following error. 'Specified cast is not valid' since the Smartobject kind of works like a black box I can't see any way to troubleshoot what exactly is happenning. Any help or pointers would be greatly appreciated.
