Adding a table to an existing table results in wrong link

Question

This is the code being used to add a table to a report:
private ISCRTable AddLinkTable(ILinkTable linkTable, string sourceTableAlias, ConnectionInfo connectionInfo)
{ // construct a new Table from its name
ISCRTable newTable = new Table();
newTable.ConnectionInfo = connectionInfo.Clone();
newTable.Name = linkTable.LinkTableName;
newTable.Alias = linkTable.LinkTableName + "_ThisIsTheLinkTable" + LinkTableId++;
if (_dataServiceSettings.DataProvider == DataProvider.Oracle11G)
newTable.QualifiedName = _dataServiceSettings.DatabaseUserName.ToUpper() + "." + newTable.Name.ToUpper();
else
newTable.QualifiedName = "dba." + newTable.Name;
// add a field to this new Table
newTable.DataFields.Add(AddDbField(linkTable.DataField, newTable.Alias));
// join this table to another one named sourceTableAlias, using linkFields TableLink
tableLink = new TableLink();
tableLink.SourceTableAlias = sourceTableAlias;
tableLink.TargetTableAlias = newTable.Alias;
tableLink.JoinType = CrTableJoinTypeEnum.crTableJoinTypeEqualJoin;
Strings sourceFields = new Strings();
Strings targetFields = new Strings();
for (int i = 0; i + 1 < linkTable.LinkFields.Length; i += 2)
sourceFields.Add(linkTable.LinkFields[i]); targetFields.Add(linkTable.LinkFields[i + 1]);
tableLink.SourceFieldNames = sourceFields;
tableLink.TargetFieldNames = targetFields;
TableLinks tableLinks = new TableLinks();
tableLinks.Add(tableLink); _report.ReportClientDocument.DatabaseController.AddTable(newTable, tableLinks);
_report.ReportClientDocument.DatabaseController.VerifyTableConnectivity(newTable);
//AddFieldToReport("{" + newTable.Alias + "." + linkTable.DataField + "}");
return newTable;
This is the resulting query SELECT "Article"."ArtId", "Article"."ArtDescr", "ArticleGroup"."AgDescr1", "Article"."ArtPurchLevel", "Article"."ArtMaximum", "Article"."ArtAbc", "Article"."ArtContext", "Article"."ArtPurchPrice", "Article"."ArtServOutUnt", "ArticleSite"."ArtsSitId", "Article"."ArtRecStatus"
FROM  (dba.Article "Article" LEFT OUTER JOIN dba.ArticleGroup "ArticleGroup" ON "Article"."ArtAgId"="ArticleGroup"."AgId")
INNER JOIN "10_78_00"."dba"."ArticleSite" "ArticleSite" ON "Article"."ArtId"="ArticleSite"."ArtsPurch" WHERE  "Article"."ArtContext"=1 AND ("ArticleSite"."ArtsSitId"='63'
OR "ArticleSite"."ArtsSitId"='64') AND "Article"."ArtRecStatus">=0 ORDER BY "Article"."ArtId"
the link field artspurch is not the field I declared . It happens to be the first column of the table ArticleSite. This seems to be a bug. has anyone ever experienced anything like this?

Hi Henk,
What was the SQL before you added the table?
I reformatted your code but you may want to confirms it correct or simply copy it into Notepad and then paste into this post.
I find the easiest way to confirm is ad the table and joins in CR Designer first and then look at what Debug mode returns using this:
btnReportObjects.Text = "";
string crJoinOperator = "";
foreach (CrystalDecisions.ReportAppServer.DataDefModel.TableLink rasTableLink in rptClientDoc.DataDefController.Database.TableLinks)
    //get the link properties
    btnCount.Text = "";
    int y = rptClientDoc.DataDefController.Database.TableLinks.Count;
    btnCount.Text = y.ToString();
    string crJoinType = "";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeAdvance)
        crJoinType = "-> Advanced ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeEqualJoin)
        crJoinType = "-> = ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeGreaterOrEqualJoin)
        crJoinType = "-> >= ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeGreaterThanJoin)
        crJoinType = "-> > ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeLeftOuterJoin)
        crJoinType = "-> LOJ ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeLessOrEqualJoin)
        crJoinType = "-> <= ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeLessThanJoin)
        crJoinType = "-> < ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeNotEqualJoin)
        crJoinType = "-> != ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeOuterJoin)
        crJoinType = "-> OJ ->";
    if (rasTableLink.JoinType == CrTableJoinTypeEnum.crTableJoinTypeRightOuterJoin)
        crJoinType = "-> ROJ ->";
    textBox1 = "Only gets Link type:" + rasTableLink.SourceTableAlias.ToString() + "." + rasTableLink.SourceFieldNames[0].ToString() +
        crJoinOperator + "." + crJoinType + rasTableLink.TargetTableAlias.ToString() + "." + rasTableLink.TargetFieldNames[0].ToString() + "\n";
    btnReportObjects.Text += textBox1;
    btnReportObjects.AppendText(" 'End' \n");
There are some join types RAS is not capable of.
Attach the report before and after you manually add the join and I'll see if I can get it to work also.
