set failureRateKind to DERIVED

medini_1036016653

Dear forum members,

I'm trying to programatically set a failure mode's property "failureRateKind" to DERIVED. I'm already successfully traversing all failure modes, but unfortunately the following assignment fails:

	FM.failureRateKind = Metamodel.safetyModel.FailureRateKind.DERIVED; // modify failure rate kind

with

Failed to execute Java Script: org.eclipse.emf.ecore.impl.EEnumLiteralImpl cannot be cast to de.ikv.medini.metamodel.safetyModel.FailureRateKind

I tried to look for a solution regarding the improper types (casting?!) in the forum but had no success.

Does anybody have an idea?

Thank you

Peter

Hi Peter

I have similar script in house working fine with :

FailureMode_Of_interest.failureRateKind = Metamodel.safetyModel.FailureRateKind.DERIVED.instance;

I have not the level of knowledge of Jan ;o) but maybe try.

Dear Florent,

WOW! Thank you very much for your fast and very helpful reply. The *magic* was to use ".instance". It works like a charm!

Have a nice weekend,

Peter

Jan described this aspect in https://medini.freshdesk.com/support/discussions/topics/1000091859

Now anyone searching for the error message can find his way to the solution.

PS. We tried to overcome this ".instance tail" but without success so far, hope we will get rid of it any time soon.

Dear Jan,

it's alright I guess, although this pitfall could be described more prominently in the scripting guide.

Kind regards

Peter

Good idea Peter.

Lets see what is faster, adding the documentation or overcome this limitation :-)
