The following table describes the query string parameters that you can use to get additional
information:
For more information about application configuration, see Chapter 39, “Administering Flex,” in
Developing Flex Applications.
Working with a multitier application model
In MXML, you use tags to declare an applications user interface. You also use tags to declare an
applications data management tier, which represents connections to data sources, data requests
and responses, data storage, binding of data between the user interface and data sources, data
validation, and data formatting. Using just tags, you get a great deal of built-in code execution
that ties the user interface to the data management tier. You can also write ActionScript code that
executes at runtime based on user interaction or system events.

?showAllWarnings=true
Displays warning messages.
?showBindingWarnings=true
Displays warnings about data bindings. The
showBindingWarnings parameter is a subset of the
showAllWarnings parameter. If showAllWarnings is set to true,
binding warnings are enabled. If
showAllWarnings is set to false,
setting
showBindingWarnings to true enables binding warnings.
