Garrett,

You have access to the ProcessContext from the RHS side of a rule via the kcontext variable. To start a process from the RHS, u can use the following code.

kcontext.getKnowledgeRuntime().startProcess("proceeeFoo");

Kris,

Thanks for the advice on this.  Is it possible for the constraint of type 'rule' to be a link to an existing rule?  This would preserve all the goodness of being able to be viewed by analysts in Guvnor, use DSLs, etc.

Alternatively, as you mentioned that internally Drools, translates this form to my 2nd option, is there an example that shows a rule with the RHS starting the process?

Thanks,
Garrett

Garrett,

The 3rd option you describe is currently possible in the core engine, however support has not yet been added to the graphical designer for this. You can however manually add it in the XML directly for now.  If you look at the XSD it should look something like this:

<start id="1" name="Start" >
<triggers>
 <trigger type="constraint" >
   <constraint type="rule" dialect="mvel" >p:Person()</constraint>
   <mapping type="in" from="p.getName()" to="SomeVar" />
   <mapping type="in" from="&quot;SomeString&quot;" to="SomeOtherVar" />
 </trigger>
</triggers>
</start>

As you can see you can also specify additional parameters (that are passed in as variables to the process instance), either by relating them to a parameter of the rule or by specifying an explicit value.

Note that it is internally simply translated to your 2nd option.

We'll try to add the editor for this property for the Drools.5.0.0.GA release.

Kris
