Hi all,
to handle the new Java 5 object type (enum), I started a test project to
handle the enums.
I simply define an object to be persisted called TestEnum. It has two
attributes, an LangEnum (enum) and an integer.
In my xml config file I defined the type handler for this attribute. After
starting the test, getting objects works well. Saving fails due to
NullPointerException. Debugging shows, that the type handler is null!
I'm using iBaits 2.1.5 and JDK 5.0.01.
Thanks in advance.

Here the sqlMap and then the exception:
<sqlMap>
<typeAlias type="test.enums.TestEnum" alias="testEnum"/>
<resultMap id="testEnum" class="testEnum">
<result property="id" column="id"/>
<result property="currentLang" column="lang"
javaType="test.enums.LangEnum" typeHandler="test.enums.TypeHandlerEnum"/>
</resultMap>
<select id="getAll" resultMap="testEnum">
select * from test_enum
</select>
<insert id="save" parameterClass="testEnum">
insert into test_enum (lang) values (#currentLang#)
<selectKey keyProperty="id" resultClass="int">
select LAST_INSERT_ID()
</selectKey >
</insert>
</sqlMap>
and the exception:
test.enums.TestEnum: id=1, lang=CH
