Web Wizard Dialog implementation: Startup.
This class contains the startup implementation and session mounting methods.
<h2> Data Aware Concept </h2>
<p> I use DataAware objects, which synchronize
UI and Data. A DataAware object a kind of interface
between a Value and a UI element.
</P>
<p>
A Value is either a JavaBean property with
a Getter and a Setter or a public class Member.
</P>
When the UI Control changes, the Value changes correspondingly.
This depends on WWD_General.settings a Listener which calls the updateData()
method od the DataAware object.
When the Value changes, the UI Control changes respopndingly.
This also depends on WWD_General.settings a Listener which calls the updateUI
method of the DataAware object.
</P>
<P>
here I use only UI Listeners, and keep calling
the updateUI() method whenever I change the Value.
</P>
To contain the Data, I use the Configuration Data Objects
which read themselves out of the Configuration. they are all located under
the data package.
<p/>
Different groups of DataAware objects are grouped into vectors.
Each group (all elements of a vector) uses the same DataObject,
so when I change the underlying dataObject, I change the whole vector's
DataObject, thus actualizing UI.<br/>
This is what happens when a session loads: I Load the session into
a tree of DataObjects, and change the DataAware's DataObject. <br/>
One could also look at this as a kind of "View-Model" relationship.
The controls are the View, The DataObjects are the Model, containing the
Data rad directly from the configuration, and the DataAware objects
are the controller inbetween.
