The issue occurs after doing the followiing:

• use Teiid Connection importer create source model
• create view model
• try data preview on view table

This issue is that your prompted with message:
"Required data source is not deployed to the server, do you want to do it?"

When a source model is created by Teiid Connection importer, that prompt should not occur, because the data source already exist. However, if it does exist, it should allow you to continue to try to execute preview. Right now its create data source or nothing.
