When creating an entity via POST message, it is expected, that the returned message includes the primary key of the newly created instance. This is not the case currently -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: TEIID-5599 URL: https://issues.jboss.org/browse/TEIID-5599 Project: Teiid Issue Type: Bug Reporter: Christoph John Assignee: Steven Hawkins Priority: Critical Fix For: 12.1 The following communication shows the issue. What I am doing here is to create a new Account entity via post request. My underlaying mysql database requires the primary key in the table to be set to NN (not null), hence, a value must be provided. Moreover the primary key is set to autoincrement and is generated by the database. The only execepted value here seems to be, to provide the key with value=0. The object is created in the database as expected. However, Teiid answers with the created object, but again with the primary key (idProfile) set as zero, instead to provide the newly created primary key.
