> Key: IBATISNET-166
> URL: http://issues.apache.org/jira/browse/IBATISNET-166
> Project: iBatis for .NET
> Type: Bug
> Components: DataMapper
> Versions: DataMapper 1.3
> Environment: Microsoft Windows Server 2003, DotNetFramework 1.1
> Reporter: cristian manea

> The pdf documentation, Chapter 3, 3.5.13. Composite Keys or Multiple Complex
> Parameters Properties, says:
> "However, there is an alternate syntax that allows multiple columns to be
> passed to the related mapped statement. This comes in handy for situations
> where a composite key relationship exists, or even if you simply want to use
> a parameter of some name other than #value#. The alternate syntax for the
> column attribute is simply {param1=column1, param2=column2, ...,
> paramN=columnN}."
> Instead I found there will be ALWAYS the error: "columnN}" while getting the
> value from the query; i have downloaded the source and I have identified the
> point where the error is made: the split of the column does not consider the
> fact the the } and { are part of the string.
> It will work only if we don't use the { and } when defining the column
> property in the sqlmap definition (but in this way, the specification for the
> column property is not followed). It olny works by not following the
> specifications :) :).
> --- column="idlabel=desc_fk,idlanguage=id_language" ----
> Source code in "MappedStatement.cs", project "IbatisNet.DataMapper" where I
> have identified the error:
> private void SetObjectProperty(RequestScope request, ResultMap resultMap,
> ResultProperty mapping, ref object target, IDataReader reader) ,
> ...............................
> if (paramString.IndexOf(',')>0 ||
> paramString.IndexOf('=')>0) // composite parameters key
> {
> IDictionary keyMap = new Hashtable();
> keys = keyMap;
> // define which character is seperating
> fields
> char[] splitter = {'=',','};
> string[] paramTab =
> paramString.Split(splitter);
> if (paramTab.Length % 2 != 0)
> {
> throw new
> DataMapperException("Invalid composite key string format in
> '"+mapping.PropertyName+". It must be:
> property1=column1,property2=column2,...");
> }
> IEnumerator enumerator =
> paramTab.GetEnumerator();
> while (!wasNull &&
> enumerator.MoveNext())
> {
> string hashKey =
> ((string)enumerator.Current).Trim();
> enumerator.MoveNext();
> object hashValue =
> reader.GetValue( reader.GetOrdinal(((string)enumerator.Current).Trim()) );
> keyMap.Add(hashKey, hashValue );
> wasNull = (hashValue ==
> DBNull.Value);
