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=""SomeString""
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.
