Class Description
This class provides the behavior for the error page Direct to Web templates, specifically BASErrorPage, NEUErrorPage, and WOLErrorPage. The classes for these pages inherit directly from D2WErrorPage and define no additional methods or variables.
Most of the methods in this class are accessed (via the EOKeyValueCoding interface defined in the EOControl framework) from the Direct to Web template's bindings (.wod) file. If you create a Direct to Web template from an error page, you can invoke the methods in this class in the same way. See the "Direct to Web" chapter of WebObjects Tools and Techniques for more information about creating a Direct to Web template.

public String firstLineOfMessage()

formattedMessage
public String formattedMessage()
Returns a String containing a version of the error message with line breaks added so it fits on the page.
hasNextPage
