Issues with previewing data after switch from 7.7.x Teiid to 8.2.x Teiid default server --------------------------------------------------------------------------------------- Key: TEIIDDES-1605 URL: https://issues.jboss.org/browse/TEIIDDES-1605 Project: Teiid Designer Issue Type: Feature Request Components: Data Preview, VDB & Execution Affects Versions: 8.1 Reporter: Barry LaFond Assignee: Paul Richardson Fix For: 8.1 After switch from 8.2.x Teiid server to 7.7.x Teiid server, closing the project and deleting the Preview VDBs from the local files system (local eclipse workspace)..... * Opened Project * Tried to Preview a table and got an NPE: ** java.lang.NullPointerException at org.teiid.designer.runtime.preview.PreviewManager.getFullDeployedVdbName(PreviewManager.java:642) at org.teiid.designer.runtime.preview.PreviewManager.previewSetup(PreviewManager.java:1373) at org.teiid.designer.runtime.ui.preview.PreviewDataWorker$1.run(PreviewDataWorker.java:233) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) The method failing is: private String getFullDeployedVdbName(ITeiidVdb deployedVdb) { String fullVdbName = deployedVdb.getPropertyValue("deployment-name");; if (!fullVdbName.endsWith(Vdb.FILE_EXTENSION)) { fullVdbName = fullVdbName + Vdb.FILE_EXTENSION; } return fullVdbName; } ITeiidVdb is a new SPI interface. So was the "deployment-name" property available with Teiid 7.7.x runtime? Also can't Undeploy VDB on 7.7.2 server
