Troubleshooting

This troubleshooting information is new for Sybase Unwired Platform version 1.2.1.

• Restrictions for Configuring Unwired Server Properties
  Configure Unwired Server properties only from the Administration Console or by editing the sup.properties file.
• Argument and Column Name Length Limitations
  Mobile business object (MBO) argument and column names have no character length limits.
• Cannot Preview Data
  Problem: In some cases, Unwired WorkSpace cannot extract the metadata that is required for a preview through the JDBC driver. In these cases, Unwired WorkSpace either executes the mobile business object's SQL statement to extract the metadata from the preview results, or executes a remote procedure call to get the results.
• Troubleshooting Mobile Business Object Web Service Deployment Failures
  Problem: If a Web service contains a parent and a child hierarchical data structure, and the parent and child have columns that have the same name, the mobile business object using this interface cannot be deployed on the server. An error message displays during deployment.
• Default Values are not Recognized as Synchronization Values
  Set the sync parameter value before every synchronization from the device application if the default value is not recognized as a sync value.
• SQLE_TOO_MANY_PUBLICATIONS Error
  Problem: If there are more than 30 syncable mobile business objects (MBOs) in a package, and fewer than 30 syncable MBOs in the Device Application Designer file, a SQLE_TOO_MANY_PUBLICATIONS error may occur when you synchronize the MBOs on Windows Mobile.
• Device Application Designer Does Not Generate GUI Fields
  Problem: The Device Application Designer does not generate graphical user interface (GUI) fields for enterprise information system (EIS) connection property parameters in device applications (especially for SAP applications).
• Trailing Space Causes Synchronization Failure
  Problem: If you attempt to synchronize a mobile business object (MBO), and its key column includes values that differ only by a space; for example, "test" versus "test ", synchronization fails.
• BlackBerry Devices Display a Maximum of 6000 Records
  Problem: BlackBerry devices encounter out-of-memory errors when trying to display more than 6000 records (rows) of data.
• Troubleshooting Windows Mobile Device Applications
  Problem: When trying to open a device application on a Windows Mobile device, a Cannot instantiate Ctl_image.FormUntitled1(application name) [Can not instantiate Form of type FormUntitled1] error is received.
• Synchronizing Device Applications that Reference Related Mobile Business Objects
  Problem: If you synchronize from a child screen of a device application, and if the parent data is missing, old data still appears in the child screen. (Parent data may be missing either because back-end data has been deleted, or because of a changed synchronization condition, such as modified personalization keys.)
• Generation Failed Error When Generating a Device Application
  Problem: When generating a device application that uses localization in the Device Application Designer, a "Generation Failed: The locale that contains the basic locale of locale must be included " error is received.
• Missing Sync Parameter Error Message on the BlackBerry Simulator
  Problem: After generating the device application code in the Device Application Designer, launching the BlackBerry Simulator, and synchronizing the device application, a "Missing Sync Parameter" error appears.
