5. Known problems
5.1 DataWindow .NET issues
5.1.1 GetFullState and SetFullState cause OutOfMemoryException
When used with a large volume of data in a distributed (.NET remoting) application, the GetFullState and SetFullState methods consume excessive memory and an OutOfMemoryException is thrown. The same technique in a client/server application works correctly. [CR 360283]
5.1.2 ADO.NET driver does not support Oracle stored procedures
The DataWindow .NET ADO.NET database driver cannot retrieve a DataWindow built using an Oracle stored procedure as its data source. It reports the following error: “SqlDbCode = 999. SqlErrText = Select error: Requested result set not found.” The same DataWindow can be retrieved successfully using the DataWindow .NET Transaction object. [CR 347692]
5.1.3 DataWindow blobs do not support Web services
The DataWindowFullState and DataWindowChanges classes cannot be used in a Web service because some of their members are internal or protected and therefore cannot be serialized using XML serialization. [CR 404157]
5.2 DataWindow issues
5.2.1 AutoSize Height issues with header band
When two reports are included one above the other in the header band of a DataWindow object and the AutoSize.Height property is set to true for the header band and false for the detail band, the DataWindow displays incorrectly in preview. The lower report overlaps the upper report. The report displays correctly if the Autosize.Height property is set to true in both the header and detail bands.[CR 405033]
5.2.2 Save As PDF fails on Windows 2003 Server
Saving as PDF fails at runtime on Windows 2003 Server. This is caused by a Group Policy that by default disallows installation of printers that use kernel-mode drivers. Kernel-mode drivers have access to system-wide memory, and poorly written drivers can cause system failures. To allow installation of kernel-mode drivers, follow these steps:
Select Run from the Windows Start menu.
In the Open box, type gpedit.msc and click OK.
In the Group Policy console, expand Computer Configuration, Administrative Templates, and Printers.
Disable “Disallow Installation of Printers Using Kernel-Mode Drivers.”
5.2.3 Limitations in default PostScript drivers
The PostScript drivers installed with DataWindow .NET do not support searching the generated PDF file, and when a DataWindow object has more columns than fit on a single page, so that data is wrapped to a new page in the PDF file, sometimes the last column on each page is clipped. The workaround is to use an alternative driver. See the Installation Guide for how to install and use an alternative driver. [CR 324579, CR 332365]
5.3 Web DataWindow issues
5.3.1 Page error when page scripting language set to VBScript
5.3.2 ResetUpdateStatus in external Web DataWindow
When a DataWindow has been retrieved from a database, calling ResetUpdateStatus after InsertRow resets the client context and no row is inserted on the client. This is expected behavior. However, when a DataWindow has been created using DataWindowSyntaxFromSql, the client context is not reset and a row is inserted on the client. If you make another change before calling ResetUpdateStatus, such as calling SetItem, the client context is reset and no row is inserted. [CR 380438]
5.3.3 Web DataWindow Retrieve fails with retrieval arguments
When there are retrieval arguments, the Web DataWindow client-side Retrieve method returns -1 and fails to retrieve data. [CR 382988]
5.3.4 Rectangles not rendered in Label Web DataWindow
Rectangles in the foreground layer of a label DataWindow cannot be rendered unless the WebDataWindowControl's height is set to a fixed value. [CR 414976]
5.3.5 In correct rendering after client-side insert, append, or delete
In an N-Up DataWindow using the XML RenderFormat and XmlClientSide PagingMethod, some items in the detail band, such as a computed field or text, are rendered in the wrong position after a client-side insert, append, or delete row. Newly inserted or appended rows are not rendered correctly. [CR 423620]
5.4 Database connectivity issues
5.4.1 Window is a reserved word in ASA
Set the DelimitIdentifier database parameter to “Yes” in the ConnectString.
Set the ASA database option “SET OPTION NON_KEYWORDS = ‘WINDOW’”.
In SQL statements, enclose the column name in quotation marks.
5.4.2 Informix interface does not work with UTF-8
The IN9 Informix database interface cannot update and retrieve data when the Informix server uses the UTF-8 character set. The interface works correctly with ANSI and DBCS. [CR 349535]
5.4.3 Alter table limitations with OLE DB and Microsoft SQL Server
When you connect using OLE DB and change the name or width of a column in an MSS2000 database using Alter Table in the Database painter in DataWindow Designer, the column is moved to the end of the table and all its data is lost. To prevent this from occurring, DataWindow Designer does not allow you to alter a table's column name and column size. You can alter the table outside the painter using ISQL scripts. [CR 348581]
5.4.4 OraOleDB faster than Oracle8ADOProvider
When you use an OLE DB connection to an Oracle9idatabase, the Table list or View list displays more quickly in the Database painter if you use OraOleDB instead of the Oracle8ADOProvider. [CR 341835]
5.4.5 Connection issues with CnnPool
In the Database painter, attempting to connect to an Oracle9i or Oracle 10g database from an Oracle9i or Oracle 10g client fails after a connect and disconnect if the CnnPool database parameter is set to ‘Yes’. [CR 355639]
5.4.6 Microsecond portion of Adaptive Server times not retrieved
When you use the OLE DB interface to connect to an Adaptive Server Enterprise database and select a column with the DateTime or Time datatype, the microsecond portion of the time value is not retrieved. When you use the ODBC and JDBC interfaces, the microsecond portion of a DateTime column value is retrieved correctly, but the microsecond portion of a Time column value is not. [CR 399257]
5.4.7 ASE version 15 with ODBC driver
NChar(10) and NVarChar(10) columns are saved as Char(10) and VarChar(10). [CR 408710]
Retrieving and updating data in a DataStore with a TimeStamp datatype fails. This is due to a bug in the ASE ODBC driver. [CR 408684, CR 416248]
