> While using EJBQLQuery, the alias name is not working if it is in mixed case
> and throws some exception saying: "unmapped id variable:"
> Eg:
> Working:
> EJBQLQuery query = new EJBQLQuery("SELECT artistAlias from Artist artistAlias
> JOIN artistalias.paintings paintingsAlias where artistalias.artistName =
> 'Abcd');
> Not Working:
> EJBQLQuery query = new EJBQLQuery("SELECT artistAlias from Artist artistAlias
> JOIN artistAlias.paintings paintingsAlias where artistAlias.artistName =
> 'Abcd');
> We declared the alias variable as "artistAlias" but it is not working if you
> say artistAlias.artistName and working if you say artistalias.artistName
> In Compiler.java class, visitFromItem... method
> while adding the alias variable name in the dictionary we convert it into
> lower case
> // per JPA spec, 4.4.2, "Identification variables are case insensitive."
> String id = normalizeIdPath(expression.getId());
> ClassDescriptor old = descriptorsById.put(id, descriptor);
> but in visitPath... method while retrieving the alias variable name from the
> dictionary we are not converting to lower case.
>
> this.id = ((EJBQLPath) expression).getId();
> this.descriptor = descriptorsById.get(id);
> if (descriptor == null) {
> throw new EJBQLException("Unmapped id variable: " + id);
> }
