<i>delegate</i> allows you to delegate this workitem to the store of another participant or directly to another participant.<br>
Some participants may be automatic agents that don't have any store, that's why direct delegation is possible to reach them.<br>
Each user may have a different set of delegation rights.<br>
Changes made to the workitem will be kept.<br>
<br>
<i>proceed</i> forwards the workitem back to the engine that will take care of resuming the flow.<br>
<br>
<i>save</i> will simply keep the changes made to the workitem and put it back in the worklist. It will also take care of unlocking it. So users that also have access to the store may use it too.<br>
<%

<i>launch</i> will launch the desired flow with the fields that were entered.<br>
<%
