Hi Niek,
I need to level set to understand what you are trying to accomplish. My understanding was that you wanted to retain the benefit of RETE, so not have that very complicated "if (true)" template code, and not have RMA coding guard clauses.
My suggestion of the multilayer "if" condition is a way to code the guard clauses in the template (so that RMA users are not even aware of them), the clauses will correctly allow RETE to operate, and the RMA users will just make selections in the RMA and the template will contain the proper guard clauses which will prevent exceptions.
My assumption is that the RMA users are creating rules that will operate on all the potential instances. One thought is to add a pattern to the ruleset and code a quantified expression on the pattern that only passes elements with the necessary properties present. That expression can have the necessary qualifications "such that damagedItem.vehicle is available" so that the individual rules are simpler.
