When you run an application that turns the trace on, a detailed log of data binding and web
services events and actions appears in the Output window. The following image shows the log for
the application created in
the trace log is added to the first frame of the application:
The following list describes the types of things reported:
•
Executing bindings
•
Calling web service methods
•
Fetching XML documents
•
Status and result events from WebService and XML components
•
Valid and invalid events from validated data fields
•
A variety of errors, invalid settings, and so on
By running your application and then examining the log, you can often find out why things are
not working as expected. Sometimes an error is explicitly reported—for example, a missing web
service parameter. Sometimes the data is bound to the wrong component or to no component
and so on. If you find that there is too much information in the log, clear the Output window by
selecting Clear from the context menu, to keep the log as short as possible.
For more information, see the "Log class (Flash Professional only)" in Using Components.
Data binding in Flash Player 7 versus Flash Player 6
Bindings between components are executed based on default component events (for example, a
binding between the
record is selected in the DataGrid or DataSet. After the event is generated, the binding is queued
to be executed as soon as possible. This action depends on your version of Flash Player. If you
publish to Flash Player 7, the binding happens immediately. If you publish to an earlier version of
Flash Player, the binding is queued to the beginning of the next frame.
However, the DataSet component works only in Flash Player 7. Queuing bindings to the next
frame can potentially cause issues with components, such as the DataSet, that provide their own
events for accessing data that may become out of sync with data binding. To avoid these issues,
Macromedia recommends that you publish to Flash Player 7 when using the DataSet component.
