Subject [jira] Commented: (IBATISNET-168) The parameter class reflection does not work anymore

------------------------------------------

Hello, I'm still Cristian Manea.

I was able to BYPASS the problem by eliminating the parameterClass property from ALL the select
statements in my sqlMaps.

<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> 

I think the problem comes from that new "Probe" that is done when parsing the maps. As a humble
opinion: at least until one is 100% sure, the "anomalies" found by the new probe object should
not block everything by throwing an error...maybe they shoud be only treated as some kind
of warning and nothing more. 

It is clear that not giving the probe a chance to work (since i'm not telling it what class
I'm passing as a parameter), it works as in the previous version (which did not have the probe).

Best regards.

>             Project: iBatis for .NET
>          Issue Type: Bug
>          Components: DataMapper
>    Affects Versions: DataMapper 1.5
>         Environment: Windows 2003 server, dot net framework 2.0, VS2005

> 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>
