I was basically trying a few different constructs but the following is not
valid:
package testing
import testing.AddressDetail
expander crm.dsl
function void doSomething(String s) {
System.out.println(s);
}
rule "MandatoryStreet1AddressNotNull"
when
The first street address line is empty
Send 'in when' to doSomething <-- If I take this line out then it's
legal but with it in I get the stack trace below
then
Add the message that the first street address cannot be empty
Send 'do something' to doSomething
end

The .dsl file is as follows:
#Customer Relationship Management domain specific language.
[when]The first street address line is empty=$ad : AddressDetail(street1 ==
"")
[when]The postcode is empty=$ad : AddressDetail(postcode == " ")
[then]Add the message that the first street address cannot be empty=
System.out.println("Enter the street address dummy");
Send '{s}' to doSomething=doSomething("{s}");
I realise it's a bit of dumb example but for arguments sake, doSomething may
be performing a bit more of a complex evaluation.
