I believe I have it... "declare" is meant to be used for easy
generation of java classes, so that rules can instantiate objects and
use them as such. For dynamic data models, "template" is a better fit,
as getField etc are geared towards map-like data structures.<br>
<br>
I believe that I could have :<br>
<br>
template "Address"<br>
String line1<br>
String line2<br>
end<br>
<br>
template "Person"<br>
String name<br>
int age<br>
Object address<br>
end<br>
<br>
rule "Test"<br>
when<br>
add: Address(line1 == "address")<br>
person: Person(address == add)<br>
then <br>
...<br>
<br>
Is this correct?<br>
<br>
Cheers <br>

If I declare a drl file to have the following declarations
<br>
<br>
declare Address
<br>
line1 : String
<br>
line2 : String
<br>
end
<br>
<br>
declare Person
<br>
name : String
<br>
age : int
<br>
address : Address
<br>
end
<br>
<br>
it will create Java Pojo classes for me. However, I had it all working
using fact templates, except for the address item. Is it possible to
insert fact implementations based on templates, while declaring
TypeDeclarations in the drl? (I now go to look for how to specify the
format = TEMPLATE for the drl)
<br>
<br>
I say this because I'm looking up values using id strings - e.g. the
exact same way that FactTemplate based Facts does accessing. I don't
want to have to convert all my String ids to reflectively call the set
methods on the created Pojo.
<br>
<br>
Hopefully this is enough info for you 5.0 developers - I'm still trying
to wrap my head around it all.
