No, the constraint of an EventWait node (or the State node in Drools

Hi Macon,
You can make some highly flexible DSL's by using regular expressions and DSL
entry chaining.
See the following for an example:

So the above rules could be partially rewritten as:
rule "Monetary 1"
There are certain domains where a collection of objects is itself a member of a
different collection of objects (e.g. zips in counties in states, persons in
cars at intersections). In these domains, it would be helpful to create LHS
conditions on the individual members of the "subcollection".
Have you looked into the drools-templates subproject?
There are database driven templates (thats what I ended out using), but I
suspect since you don't want to use a Excel or a CSV, that will be too
heavyweight for you.
I haven't used the ObjectDataCompiler yet, but it seems to be what you ar

Hi,
We're using Drools Guvnor 5.0.1 in a production environment, running on

hi!
is there a way to use the templating feature just from within drools?
without the use of excel or csv or java?

different packages:

- customer-a-data.drl

Can the constraint for an EventWait node in a flow be code-based (rather
than rule-based)? The Eclipse plug-in (v 5.0.1) doesn't allow this to be
specified, unlike say for a Split node, although the relevant XML can of
course be edited.

Hi Hemanth,
Assuming that you've already tried debugging it... could you share your Fact

The jars are correct.
