https://bugzilla.novell.com/show_bug.cgi?id=672113#c0 Summary: Severe bug adding multiple columns constraints to DataTables Classification: Mono Product: Mono: Class Libraries Version: 2.6.x Platform: All OS/Version: All Status: NEW Severity: Critical Priority: P5 - None Component: Sys.Data AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: Development Blocker: Yes Description of Problem: Defining a primary key constraint in a DataTable passing a reference to an array is not implemented correctly. The DataSet stores the reference to the passed array, instead of cloning the array (Microsot .net implementation) Steps to reproduce the problem: 1. Create First DataTable 2. Declare array of two columns 3. Use array to create constraint 4. Reuse the array to create another constraint for other DataTable 5. The constraint of First DataTable is now broken DataColumn[] primkeys = new DataColumn[2]; primkeys[0] = FirstTable.Columns[0]; primkeys[1] = FirstTable.Columns[0]; FirstTable.Constraints.Add("PRIM1",primkeys,true); primkeys[0] = SecondTable.Columns[0]; primkeys[1] = SecondTable.Columns[0]; SecondTable.Constraints.Add("PRIM2",primkeys,true); The first constraint is now broken, so when adding rows to the first table results in unexpected error like: COLUMN xx does not belong to TABLE xx. Actual Results: The constraints have a reference to a single array, so the array of first table is borkin. Expected Results: Two different and independent constraints inside the DataSet How often does this happen? Allways Additional Information: This problem was discovered because side effects, problems adding rows. The initial code was in Microsoft.Net so after compiling and executing in Mono random problems with DataTables occured. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
