Hello,


I have a Webmethod

===
[WebMethod]
public void SaveDataset(DataSet ds)
{
return;
}
====

I call this webmethod from a client, passing a DataSet with an
ForeignKeyConstraint like this:

===
DataSet ds = new DataSet("NewDataSet");
DataTable table1 = new DataTable("master");
DataColumn col11 = new DataColumn("ID", typeof(int));
DataColumn col12 = new DataColumn("text", typeof(string));

table1.Columns.Add(col11);
table1.Columns.Add(col12);
DataTable table2 = new DataTable("detail");
DataColumn col21 = new DataColumn("ID", typeof(int));
DataColumn col22 = new DataColumn("FK", typeof(int));

table2.Columns.Add(col21);
table2.Columns.Add(col22);
ds.Tables.Add(table1);
ds.Tables.Add(table2);

UniqueConstraint constraint1 = new UniqueConstraint("detailIDUnique",
ds.Tables["detail"].Columns["ID"], true);
ds.Tables["detail"].Constraints.Add(constraint1);

UniqueConstraint constraint2 = new UniqueConstraint("masterIDUnique",
ds.Tables["master"].Columns["ID"], true);
ds.Tables["master"].Constraints.Add(constraint2);

ForeignKeyConstraint constraint3 = new
ForeignKeyConstraint(ds.Tables["master"].Columns["ID"],
ds.Tables["detail"].Columns["FK"]);
ds.Tables["detail"].Constraints.Add(constraint3);


service.SaveDataset(ds);
====

So far so good, this works all right.

However If I then enable Encryption and Signature on both the webservice
and the client (I use an X509 certificate and a policy file similar to
<http://msdn.microsoft.com/webservices/building/wse/default.aspx?pull=/library/en-us/dnwse/html/wse2wspolicy.asp>
) I get the following error:

===
Server was unable to read request. --> There is an error in XML document
(1, 1653). --> The 'http://tempuri.org/:masterIDUnique' identity
constraint is not declared. An error occurred at , (1, 1477).

I don't change anything in the code of either server and client, I just
uncomment the <policy> section in each of the config files and I get
this error.

I had a look a the soap envelope the webserice is recieving in each case
(with and without encryption) by using a SoapInputFilter and can't see
anything wrong with it. The xml is very slightly different (as confirmed
by XML Diff http://apps.gotdotnet.com/xmltools/xmldiff/) but nothing major.

Transfering datasets without contstraints works fine.

I have no idea what is wrong here, any help is appreciated.


In case someone is interested, here are the soap requests in both cases:


1. not using encryption -> works

===

2. using encryption, after the request is decrypted -> There is an
error in XML document

====
<?xml version="1.0" encoding="utf-8"?><soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Hi Ben,

It seems that we stoumbled over the same problem. I think it has nothing to
do with WSE 2.0.

The bug could be reproduced like this:

1.
DataColumn[] arrKey = new DataColumn[1];;
arrKey[0] = ds.Tables["Request"].Columns["RequestID"];
ds.Tables["Request"].PrimaryKey = arrKey;

DataColumn[] arrKey2 = new DataColumn[1];;
arrKey2[0] = ds.Tables["Package"].Columns["PackageID"];
ds.Tables["Package"].PrimaryKey = arrKey2;
ds.Tables["Package"].Columns[arrKey2[0].ColumnName].AutoIncrement = true;
ds.Tables["Package"].Columns[arrKey2[0].ColumnName].AutoIncrementSeed =
-1;
ds.Tables["Package"].Columns[arrKey2[0].ColumnName].AutoIncrementStep =
-1;


In this case the exception would be:

There is
an error in XML document (1, 4321). --> The
'http://tempuri.org/:Request_Constraint1' identity constraint is not
declared. An error occurred at , (1, 3905)."}


2.

DataColumn[] arrKey2 = new DataColumn[1];;
arrKey2[0] = ds.Tables["Package"].Columns["PackageID"];
ds.Tables["Package"].PrimaryKey = arrKey2;
ds.Tables["Package"].Columns[arrKey2[0].ColumnName].AutoIncrement = true;
ds.Tables["Package"].Columns[arrKey2[0].ColumnName].AutoIncrementSeed =
-1;
ds.Tables["Package"].Columns[arrKey2[0].ColumnName].AutoIncrementStep =
-1;

DataColumn[] arrKey = new DataColumn[1];;
arrKey[0] = ds.Tables["Request"].Columns["RequestID"];
ds.Tables["Request"].PrimaryKey = arrKey;

In this case the exception would be:

There is
an error in XML document (1, 4321). --> The
'http://tempuri.org/:Package_Constraint1' identity constraint is not
declared. An error occurred at , (1, 3905)."}

which leads us to a conclusion that XML parser always skips Constraint
Definition for the first table and WSE2.0 just reports the error.


Take a look at my webservices.enhancements group message: WSE2 identity
constraint is not declared problem
