Description
I generate source and view model from flat file. Preview data works fine. I create VDB and test it. I use the same query ( select * from "ViewModelForFlatFile"."viewTable" ) as for the preview but it failed.
Error:
org.teiid.runtime.client.TeiidClientException: java.lang.RuntimeException: Remote org.teiid.core.TeiidProcessingException: TEIID30504 SourceModelForFlatFile: Inproper results returned. Expected 5 columns, but was 2
Error log from a server:

This issue is only when a flat file is local (because remote flat file uses another function in the source model (invokeHttp)).
The same issue is with XML file.
We noticed that old designer generated ReusltSet for procedure getTextFiles in the Source model with two parameters (file and filePath) but new designer generates ResultSet with five parameters (file, filePath, lastModified, created, size). This may be a problem.
