OCL how to do not have duplicates in a result

Question

Dear All

I have this script to detect which causes are linked to a measure in a FMEA.

self.mediniGetOpposites('detectionMeasures').oclAsType(safetyModel::MeasureGroup).mediniGetOpposites('element').oclAsType(FMEA::MeasureEntry).failureCause->asSet()

But when we have the same cause for different Failure modes, this script detects 2 or 3 times the same cause

Do you have a solution, perhaps replace asSet() by other thing, when i put first() i have only the first cause ?

Thank you in advance

It works

Perfect

Many thanks

Hi Philippe,

ah, I understand. So this should do it:

self.mediniGetOpposites('detectionMeasures').oclAsType(safetyModel::MeasureGroup).mediniGetOpposites('element').oclAsType(FMEA::MeasureEntry).failureCause.element->asSet()

and probably you can even omit the asSet().

See also on the screenshot - compared to your original script:

Note, in your original OCL you just go to the (FMEA) failureCause entries. These are all individual model elements (and have internally unique identification - even if they carry the same ID/name in the UI) - so even as a set they will occur all.

Hi Eckhardt

Thanks for your answer

But it is not my need. Actually i have 3 columns in javascript to detect for a measure the effects, the Failure modes and the causes. These scripts are able to detect the duplicates and put only one time the cause for example. However the refresh is very long, a lot line and a lot of contributions.

I want to replace javascript by ocl, but in OCL when my measure contributes in different lines of FMEA, i have all effects, FM and causes even if we already have.

asSet(), first() and asOrderedSet() don't solve this issue.

Do you have other control ?
