This is what is currently possible.
The 'nested' Facts have type Object. due to that I cannot access the Properties
directly but have to use the from clause.
If I do try to access it directly I do get an ArrayIndexOutOfBoundsException in mvel and
an (org.drools.RuntimeDroolsException: This is a bug. Please report to development team:

greywind commented on JBRULES-1440:
-----------------------------------
What I would like to be able to do is:
package org.drools.entity
template ISIN
String Identifier
end
template Identifiers
ISIN ISIN
end
template Settlement
String InstrumentType
String InstrumentName
Identifiers Identifiers
end
rule "TestEntity"
dialect "mvel"
when
$s : Settlement(InstrumentType == "BOND", name : InstrumentName, id :
Identifiers.ISIN.Identifier)
then
System.out.println("Found: " + name + ", " + id);
end
I want to use a template definition as a type in another template.

Resolution: Rejected
Assignee: Mark Proctor
I'm rejecting this for now. It's not that we won't do it, but we need to fully
review facttemplates and decide what to do with them. We'll bear this one in mind when
that happens, but no time frame for this yet.
