Just opening an XML document model causes it to be marked "dirty" ----------------------------------------------------------------- Key: TEIIDDES-54 URL: https://jira.jboss.org/jira/browse/TEIIDDES-54 Project: Teiid Designer Issue Type: Task Affects Versions: 6.0.0 Environment: Linux Reporter: Paul Nittel Assignee: Barry LaFond Fix For: 6.0.0 I started by importing the Books project. I expanded the BooksXML document model, then double-clicked the Bookcollection object in the package diagram. As soon as the mapping class diagram opened, it was shown as dirty. All I did was open it!
