Insert block with attributes side loaded DWG

[Michiel_]

Hi all,

When I try to insert a block with attributes in a side loaded dwg with the following code I get the error wrong database at the line brBlock.AttributeCollection.AppendAttribute(ar); . Can someone point me in the right direction of what I'm doing wrong?

Thanks in advance.

 using (Database targetDb = new Database(false, true))
                {
                    using (Transaction tr = targetDb.TransactionManager.StartTransaction())
                    {
                        targetDb.ReadDwgFile(file, FileOpenMode.OpenForReadAndAllShare, true, "");
                        targetDb.CloseInput(true);

                        bool bFixErrors = true;
                        bool becho = true;

                        ImportAlstomFiles.TransformDwg.InsertTbmBlock(targetDb);

                        targetDb.Audit(bFixErrors, becho);
                        targetDb.SaveAs(file, DwgVersion.Current);

                        tr.Commit();
