Hi-

I'm having trouble understanding how to use subdialogs.  How do I specify
the end state for a subdialog that also ends the calling dialog?

You'll need to take the outcome value returned by the exit state from the
subdialog, and create a transition for that to the exit state for the
calling dialog.

 The

documentation mentions some of the possiblities, but doesn't really show
how to configure it.  Is there a good example somewhere?  I looked in the
samples I downloaded, but the subdialog isn't included.  If I understand
it correctly.  In the example below (from shale-starter and sql-browser),
the subdialog "Edit Profile" is mentioned, but it isn't in
dialog-config.xml.

You're right ... if the commented out sample is going to reference a
subdialog, then the subdialog should be there too.

The actual implementation of the dialog and subdialog from which this was
taken is in the Use Cases example, where the subdialog is defined like this:

 <dialog                name="Edit Profile"
                       start="Setup">

   <!-- Global transitioh definitions -->
   <transition       outcome="cancel"
                      target="Cancel"/>
   <transition       outcome="finish"
                      target="Finish"/>

   <action              name="Setup"
                      method="#{profile$edit.setup}">
     <transition     outcome="success"
                      target="Page 1"/>
   </action>

   <view                name="Page 1"
                      viewId="/profile/profile1.jsp">
     <transition     outcome="next"
                      target="Page 2"/>
   </view>

   <view                name="Page 2"
                      viewId="/profile/profile2.jsp">
     <transition     outcome="next"
                      target="Page 3"/>
     <transition     outcome="previous"
                      target="Page 1"/>
   </view>

   <view                name="Page 3"
                      viewId="/profile/profile3.jsp">
     <transition     outcome="next"
                      target="Exit"/>
     <transition     outcome="previous"
                      target="Page 2"/>
   </view>

   <action              name="Cancel"
                      method="#{profile$edit.cancel}">
     <transition     outcome="success"
                      target="Exit"/>
   </action>

   <action              name="Finish"
                      method="#{profile$edit.finish}">
     <transition     outcome="password"
                      target="Page 1"/>
     <transition     outcome="success"
                      target="Exit"/>
     <transition     outcome="username"
                      target="Page 1"/>
   </action>

   <end                 name="Exit"
                      viewId="/usecases.jsp"/>

 </dialog>

This does a simple three-page wizard with next, previous, finish, and cancel
buttons on each page.


Thanks for your help.
