[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - NPE when creating query

[cfthomas]

Hi!

I'm using JBoss-4-1.2.1.GA with SEAM 2.0.0.CR2.
I get the following exception when creating a query

  | Caused by: java.lang.NullPointerException
  |         at org.hibernate.hql.ast.tree.FromClause.findIntendedAliasedFromElementBasedOnCrazyJPARequirements(FromClause.java:120)
  |         at org.hibernate.hql.ast.tree.FromClause.containsClassAlias(FromClause.java:247)
  |         at org.hibernate.hql.ast.tree.FromClause.isFromElementAlias(FromClause.java:135)
  |         at org.hibernate.hql.ast.HqlSqlWalker.isNonQualifiedPropertyRef(HqlSqlWalker.java:467)
  |         at org.hibernate.hql.antlr.HqlSqlBaseWalker.addrExpr(HqlSqlBaseWalker.java:4382)
  |         at org.hibernate.hql.antlr.HqlSqlBaseWalker.expr(HqlSqlBaseWalker.java:1212)
  | 

for this query:

  | select x  from com.xaidat.nippon.Article x where (( UPPER(x.code) LIKE UPPER(?1)  OR  UPPER(x.name) LIKE UPPER(?2)  OR  UPPER(x.manufacturer.name) LIKE UPPER(?3)  OR  UPPER(x.productgroup.name) LIKE UPPER(?4) ) AND ( UPPER(x.code) LIKE UPPER(?5)  OR  UPPER(x.name) LIKE UPPER(?6)  OR  UPPER(x.manufacturer.name) LIKE UPPER(?7)  OR  UPPER(x.productgroup.name) LIKE UPPER(?8) ))  order by price ASC
  | 

How can I fight this problem?

Thanks,

Thomas
