Adam Czysciak updated HHH-2997:
-------------------------------

    Attachment: hibernate2997test.zip

Attached a test case - bug occurs on Hibernate 3.2.6 as well.

Adding Expression.like() and Expression.like().ignoreCase() to the Criteria works ok.

Adding custom Expression (own class extending LikeExpression) doesn't work for ignoreCase=false - Hibernate always binds toLower()'ed value of the pattern.

Test output:

Hibernate: select test_seq.nextval from dual

Hibernate: insert into test (text, ID) values (?, ?)
DEBUG org.hibernate.type.StringType  - binding 'XyZ uniq1206517288290 blablabla' to parameter: 1

> LikeExpression doesn't handle ignoreCase flag properly when it's set to false. Uses it to build correct sql "property like ?", but doesn't use the flag inside getTypedValues - produces always lowercase value to bind.
> Attached a patch for 3.2.5
