I had those kinds of problem when I didn't have a normal getter and setter for
a property in my class.
Check the getters and setters called by your CPL.readArticles_Result and
getColor_Result maps and check if the setter are like this one.
public void setProperty(Object o) {
this.property = o;
}
public Object getProperty() {
return this.property;
}

Subject: Re: AW: Problem with complex properties mapping
Hi Michael,
I tried to implement your suggestion and it seems that I am now on the next
level of the problem.
Hi I followed your suggestion as follows:
<parameterMap id="prefColorsParams" class="java.util.HashMap">
<parameter property ="finr" />
<parameter property ="sais" />
<parameter property ="koll" />
<parameter property ="form" />
<parameter property ="arnr" />
</parameterMap>
<select id="getColorForArticle" parameterMap="prefColorsParams"
resultMap="getColor_Result">
now I get
com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in so/global/persistence/map/pdm/SqlMap.xml.
--- The error occurred while applying a result map.
--- Check the CPL.readArticles_Result.
--- The error happened while setting a property on the result object.
--- Cause: com.ibatis.common.beans.ProbeException: Could not set property
'articleColoursList' for so.global.persistence.map.pdm.ArticleMapper.
Cause: com.ibatis.common.exception.NestedRuntimeException: Error lazy loading
result. Cause: com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in so/global/persistence/map/pdm/Tobas_SqlMap.xml.
--- The error occurred while executing query.
--- Check the select distinct a.fbnr fbnr,
case when a.fbez = ''
then b.fbez else a.fbez end fbez from
sodta.bavfsl a left outer join
sodta.bavfnl b on a.finr=b.finr and
a.sais=b.sais and a.koll=b.koll and
a.fbnr=b.fbnr where a.finr=#finr# and a.sais=#sais# and a.koll=#koll#
and
a.form=#form# and a.vacp='' and a.arnr=#arnr# and a.glkz='A' order by
fbnr
.
--- Check the SQL Statement (preparation failed).
--- Cause: java.sql.SQLException: [SQL0206] Spalte #FINR# nicht in angegebenen
Tabellen.
which looks like a problem with the database, but when I run the query manually
against the DB it works.
I am quite irritated by the statement that the colum #FINR# does not exist as
#FINR# is an attribute and not a table in the SQL.
When using $$ I can see that finr is replaced by 010 which should be ok.
Any new ideas?
Greetings Torsten
