Complex properties and substitution strings parameter problem

[Nguyen Trong Hoan]

Hi!

I'm developing a web app with ibatis (2.2) and have got a problem with 
complex properties and passing substitution strings parameter for sql query 
of properties.

For example:

<sqlMap namespace="user">
    <resultMap id="User" class="bean.User">
        <result property="id" column="id"  />
        <result property="name" column="name" />
        <result property="address" column="id" select="getAddress"/>
    </resultMap>

    <select id="getUser" parameterClass="int"  resultMap="User">
        SELECT id,name FROM $schema$.tbl_user WHERE id = #value#
    </select>

    <select id="getAddress" parameterClass="int" resultClass="string">
        SELECT address FROM $schema$.tbl_address WHERE id = #value#
    </select>
</sqlMap>

Here, bean.User class is declared as the following:
public class User {
    private String schema;
    private int id;
    private String name;
}

so, I only passed schema parameter for getUser sql, but I couldn't pass it 
for getAddress sql.
Please help me to solve this problem.
Thank you very much!
