Steven Hawkins resolved TEIID-1705.
-----------------------------------
Resolution: Rejected
We'll expect that the expression builder / criteria builder create basically valid
object representations.
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.
