I created an app that uses cmp. When I deploy my app on my computer, it works fine. However, I tried to deploy it on another computer and received this exception:
I really have no idea what cmp is...but just looking at the error, it looks like you can't connect to the SQL server, so it is returning a null resultset, or something similar. Make sure that you have registered the data source, and that is accessible/working to/on the 2nd computer.
Round these parts, posting the same question in multiple forums is bad practice. It can make it rather difficult to follow a conversation, plus folks spend time saying things that were just said.
