Description

Hello.

We have upgraded our project from dnf 1.1 to dnf 2.0 vs2005, so we have upgraded to Data Mapper 1.5 (from 1.3).

It seams that the dynamic class reflection for the query parameters does not work anymore in 1.5, in the 1.3 version it work just fine. It is really a blocking situation for us, because...it simply does not work anymore

We are using a solution where the parameter that we are passing is a "generic" one, and has this definition:

public class Query
{
private Object _DataObject;
public Object DataObject{get

{return _DataObject; }

set { _DataObject = value;}}
private Object _ParametersObject;
public object ParametersObject{get

{ return _ParametersObject; }

set { _ParametersObject = value; }}
}

Then we are passing to iBatis (by internal convention) the "parameters" embeded in the Query class, here is an example:

obj_Query.ParametersObject = Parameters; //here we are setting our Parameters object
obj_Query.DataObject = Labels[0]; //here we are setting our Business Object
objLabel = (Label) Helpers.Label().Read(obj_Query); //here we are calling by passing the query object
Assert.IsNotNull (objLabel, "Label not returned");
.............................................................................................
public override System.Object Read(System.Object obj)

{ Labels objLabel = (Label) Mapper ().QueryForObject("SelectLabel",obj); return(objLabel); }

The mapped statemend in the sqlmap file is as follows:

<select id="SelectLabel" parameterClass="Query" resultMap="LabelResult">
select *
from ll_label_language
<dynamic prepend="WHERE">
<isParameterPresent>
<isNotNull property="DataObject">
<isGreaterThan property="DataObject.Id" compareValue="0" prepend="AND">
label_language_id = #DataObject.Id#
</isGreaterThan>
<isGreaterThan property="DataObject.LabelId" compareValue="0" prepend="AND">
label_id = #DataObject.LabelId#
</isGreaterThan>
</isNotNull>
<isNotNull property="ParametersObject" prepend="AND">
language_id = #ParametersObject.LanguageId#
</isNotNull>
</isParameterPresent>
</dynamic>
</select>

iBatis 1.5 returns this error (it does not understand that the DataObject is in fact a Label, and not an Object):

failed: IBatisNet.Common.Exceptions.ConfigurationException :

• The error occurred while loading SqlMap.
• parse dynamic tags on sql statement
• The error occurred in <sqlMap resource="${root}Resources/LabelHelper.xml" xmlns="http://ibatis.apache.org/dataMapper" />.
• Check the SelectLabel.
