google spreadsheet translator using Collections.singletonList instance returned by the runtime doesn't support the set method. -------------------------------------------------------------------------------------------------------------------------------- Key: TEIID-3966 URL: https://issues.jboss.org/browse/TEIID-3966 Project: Teiid Issue Type: Bug Components: Misc. Connectors Affects Versions: 8.12.4 Reporter: marco ardito Assignee: Steven Hawkins Priority: Minor This arised as a follow-up of a forum thread, I tried to create a google spreadsheet dynamic VDB, exposing both the source as is, and also a model with a restricted view using only some fileds in the source model. from the sql client (squirrel) connnected to the vdb, but only the raw source model works, while any query to the view shows error org.teiid.core.TeiidException SQLState: 38000 ErrorCode: 0 In the thread, Steven Hawkins spotted the bug:<<The issue is that the translator is using Collections.singletonList to return the row and the engine is expecting it to be modifiable to avoid the additional copy one the value types are corrected. The SingletonList instance returned by the runtime unfortunately doesn't support the set method. >>
