                              <!--  RichFaces are built using CDK (Component Development Kit). 
                        CDK generates the library based on the meta-data, component templates and hand-written java classes.
                        What you see in the richfaces-ui-3.1.0-src.zip is a truly source, i.e. a source for CDK.
                        To the debug purpose, you need the source code that is generated by CDK before it is compiled into the binary. 
                        -->

                <title>How to use jsFunction with JSON?</title>
                <para>JsFunction and JSON can be used in many ways, for example:</para>
                         
                <para>You want to create device in a circuit diagram. Here is the number of steps for creating:</para>
                <itemizedlist>
                        <listitem>
                You drag and drop it from the toolbox in our embedded Javascript(!) graphical editor. But first only a "please wait"-ModalPanel is shown. 
                        </listitem>
                                <listitem>
                With JSFunction we come to the SessionBean and from there to the DB to fetch some Data for drawing the device in the Editor. 
                                </listitem>
                                        <listitem>
                 When the answer comes back, we asked you with a modal panel to give a name to the device. 
                                        </listitem>
                                                <listitem>
                After you click OK, the model panel disappears (and the please wait model panel shows up again) and another JSFunction call goes over the SessionBean to the DB to create the device data there. 
                                                </listitem>
                                                        <listitem>
                When the answer comes back, a JSON-String is created with all data for drawing the device (for example the given name) and the Editor is advised to draw it (and the please wait modal panel disappears again).
                                                        </listitem>

                    <para>RichFaces components use Prototype very hard. In particular, some patches
                              has been removed that are already included into 1.6.0. Adding feature
                              with exclusion makes it possible to use Prototype with version less
                              than 1.6.0. This will break some of the components.</para>
