Known problems


DataWindow .NET issues

This section lists DataWindow .NET issues.


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]


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]


DataWindow issues

This section lists DataWindow issues.


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]


Retrieve in Web Service DataWindow requires connection

When you open the DataWindow Designer plug-in, there is no default database connection. When you create a Web Service DataWindow, you must select a database profile before the DataWindow is created even though the Web Service DataWindow does not use the profile. This also occurs with DataWindows that use an external data source. [CR 439122]


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]


Web DataWindow issues

This section lists Web DataWindow issues.


Incorrect rendering of TreeView DataWindow with grid lines

In some special cases, a TreeView Web DataWindow with grid lines is rendered incorrectly in Internet Explorer. [CR 448031]


Page error when page scripting language set to VBScript

If the scripting language of an .aspx page is set to VBScript, the JavaScript inserted when a client event handler is generated from the Properties window causes an “Invalid character” page error. VBScript and JavaScript can coexist on the page as long as the default scripting language is not set to VBScript. [CR 376258]


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]


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]


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]


Incorrect 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]


Database connectivity issues

This section lists database connectivity issues.


Window is a reserved word in SQL Anywhere

In SQL Anywhere 10, the word “window” is a reserved word. As a result, SELECT statements on a column with the name window do not work correctly. There are several ways to work around this issue:

[CR 334166]


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]


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, or use the SNC native driver. [CR 348581]


Connection issues with CnnPool

In the Database painter, attempting to connect to an Oracle9i or Oracle 10g database from an Oracle9i client fails after a connect and disconnect if the CnnPool database parameter is set to ‘Yes’. [CR 355639]


ASE version 15 with ODBC driver

When you connect to an ASE version 15 server using the Sybase ASE ODBC driver, NChar(10) and NVarChar(10) columns are saved as Char(10) and VarChar(10). [CR 408710]


Installation issues

This section lists installation issues.


Asian characters display incorrectly in license file

Due to an InstallShield limitation that prevents Asian characters in UTF-8 coded files from displaying correctly, some characters in the license file in the setup wizard display as garbage characters. The display issue does not affect the validation of the license file. [CR 475827]
