[teiid-issues] [JBoss JIRA] Updated: (TEIID-1705) Encountered NPE in SQLStringVisitor for TIMESTAMPADD and TIMESTAMPDIFF

Encountered NPE in SQLStringVisitor for TIMESTAMPADD and TIMESTAMPDIFF ---------------------------------------------------------------------- Key: TEIID-1705 URL: https://issues.jboss.org/browse/TEIID-1705 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.4 Reporter: Mark Drilling Assignee: Steven Hawkins Attachments: SQLStringVisitor-Patch.txt I was using expression builder in Designer when I encountered this NPE. java.lang.NullPointerException at org.teiid.query.sql.visitor.SQLStringVisitor.visit(SQLStringVisitor.java:1280) at org.teiid.query.sql.symbol.Function.acceptVisitor(Function.java:182) at org.teiid.query.sql.visitor.SQLStringVisitor.getSQLString(SQLStringVisitor.java:164) at com.metamatrix.query.internal.ui.builder.util.LanguageObjectLabelProvider.getText(LanguageObjectLabelProvider.java:129) I think the visit method for FUNCTION in SQLStringVisitor just needs to do a null check on the first arg. I'm attaching a code patch.
