             Summary: Problems when using External Materialized Views
                 Key: TEIID-4960
                 URL: https://issues.jboss.org/browse/TEIID-4960
             Project: Teiid
          Issue Type: Bug
    Affects Versions: 9.3
         Environment: * Teiid Server 9.3.0
* Wildfly 10
* Mysql 5.7.18
            Reporter: Pedro Inácio
            Assignee: Steven Hawkins
         Attachments: server.log

The following problem occurs when, apparently, we have two views where one depend on another, and also we use External Materialization.

The dependent view is never updated due to a "Transaction already associated with request." exception.

Logs attached.

The error:
