Description

When translating an EJBQL condition we need to keep a stack tracing the type of condition. One place where this is important is EJBQLConditionTranslator.processParameter(), as currently it hardcodes the type to VARCHAR for null parameters:

context.append(" #bind($").append(boundName).append(" 'VARCHAR')");

This leads to errors, e.g. a postgresql 8.3 error:

Tests in error:
testCompareToNull(org.apache.cayenne.access.DataContextEJBQLIsNullTest)

There may be other places where such info will be useful
