[rules-users] Using Declared types in Decision Tables

Hello,

I have a question on how one can import declared types into a decision
table, that are declared in a separate DRL file. 

Take for instance the following declared type which is defined in an
isolated DRL file:

declare Offer
 id: String
 name: String
 isValid: boolean
end

This type can be used in Java code if we were to use the Knowledge base to
give us a FactType via code like:

FactType offerType = kbase.getFactType("package.to.model.offer", "Offer");

and then use them accordingly. However, i'm not sure if such an approach /
api exists for importing declared types from DRLs into decision tables.

How can something like this be done in Decision tables?

When I import the declared Offer, which isn't complied yet, the decision
table complains.

Thanks,
Uday
