The parameter class reflection does not work anymore
----------------------------------------------------
Key: IBATISNET-168
URL: http://issues.apache.org/jira/browse/IBATISNET-168
Project: iBatis for .NET
Issue Type: Bug
Components: DataMapper
Affects Versions: DataMapper 1.5
Environment: Windows 2003 server, dot net framework 2.0, VS2005
Reporter: cristian manea
Priority: Blocker
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.
