Date conversion from ASP.NET to ABL

Hello,

We encounter the following problem.  We have a website written in ASP.Net with in the backend Openedge (.Net open client)

In the asp we create a dataset :

            DataTable ttContext = new DataTable("ttContext");
            DataColumn SessionId = new DataColumn("SessionId");
            DataColumn UsrId = new DataColumn("UsrId");
            DataColumn CompanyId = new DataColumn("CompanyId");
            CompanyId.DataType = System.Type.GetType("System.Int32");
            DataColumn ProcDate = new DataColumn("ProcDate");
            ProcDate.DataType = System.Type.GetType("System.DateTime");

            ttContext.Columns.Add(SessionId);
            ttContext.Columns.Add(UsrId);
            ttContext.Columns.Add(CompanyId);
            ttContext.Columns.Add(ProcDate);

            DataTable ttTableContext = new DataTable("ttTableContext");
            DataColumn TableName = new DataColumn("TableName");
            DataColumn WhereClause = new DataColumn("WhereClause");
            DataColumn SortBy = new DataColumn("SortBy");

            ttTableContext.Columns.Add(TableName);
            ttTableContext.Columns.Add(WhereClause);
            ttTableContext.Columns.Add(SortBy);

            DataRow row = ttTableContext.NewRow();
            row["TableName"] = "test";
            row["WhereClause"] = "referte=testgdb";
            row["SortBy"] = "";
            ttTableContext.Rows.Add(row);

            hdsContext = new DataSet("dsContext");
            hdsContext.Tables.Add(ttContext);
            hdsContext.Tables.Add(ttTableContext);

In the ABL we have the following definition of temp-table and dataset :

define {&1} temp-table ttContext no-undo   
    field SessionId as character
    field UsrId     as character
    field CompanyId as integer
    field ProcDate  as datetime
.

define {&1} temp-table ttTableContext no-undo
    field TableName    as character
    field WhereClause  as character
    field SortBy       as character.

define dataset dsContext        for ttContext, ttTableContext.

In the proxygen there is a procedure that gets the dataset-handle, which is given to another procedure.

In the last, we receive the dataset (no handle).

The error we get is the following :

[09/08/13@12:03:28.219+0200] P-001896 T-003808 1 AS -- (Procedure: 'GetDossier.p' Line:0) The caller's temp-table parameter ttContext does not match to the target temp-table ttContext. (5363)
[09/08/13@12:03:28.219+0200] P-001896 T-003808 1 AS -- (Procedure: 'GetDossier.p' Line:0) Parameters for procedure GetDossier.p (table ttContext and table ttContext) do not match. (12311)

If we leave out the procdate in both asp and ABL, it works OK ?

It seems to have problems with the date coversion

Any ideas?
