Exclusive transitions or dialogs

Special forms of dialogs are the so called exclusive dialogs. They are also referred to as null or one-step dialogs. They consist of a single transition only. Use them to go into a dialog, run only one transition, and use it to end the dialog immediately afterward.

Code sample 23 shows an example.

Code sample 23:

01 <transition type="exclusive">
 02  <source>
 03      <transition-endpoint nameref="portlet1">
 04          <event qname="eX"/>
 05      </transition-endpoint>
 06  </source>
 07  <target>
 08      <transition-endpoint nameref="portlet2">
 09          <event qname="eX"/>
 10      </transition-endpoint>
 11  </target>
 12 </transition>
