Updating Multi-Value parameters while running an iLogic rule

[sergio_duran]

Hi everyone,

Is there any way to update a multi-value parameter list that is changed by another multi-value parameter list (in the same rule) while the rule is running? I'd like to get both lists updated once the rule has finished. Let me give you an example to explain my question better.

SyntaxEditor Code Snippet

MultiValue.SetValueOptions(True, DefaultIndex := 0)

If TEST = True Then
MultiValue.SetList("ABC", 10, 20, 30)
   If ABC = 30 Then 
       MultiValue.SetList("XYZ", 1, 2, 3)
   Else
       MultiValue.SetList("XYZ", 7, 8, 9)
   End If
Else 'TEST = No
MultiValue.SetList("ABC", 40, 50, 60)
   If ABC = 40 Then 
       MultiValue.SetList("XYZ", 11, 12, 13)
   Else
       MultiValue.SetList("XYZ", 90, 80, 70)
   End If
End If

When I changed the "TEST" value, ABC will be updated the first time the rule runs but XYZ isn't updated it. I need to run the rule once again to update XYZ since it will see the new list of values of ABC. Is there any way to update both multi-value parameters only running the rule once (not twice)?

Thanks!

Hi, Autodesk has some great explanations regarding the fix for this already online in the resources.

'MultiValue.UpdateAfterChange =True will cause the model (document) to Update after the parameter is changed.
'This only takes effect when you change parameters using the Parameter function

MultiValue.UpdateAfterChange = True

Hi Justin,

Thanks for your quick reply and help! I overlooked the snippet 

MultiValue.UpdateAfterChange = True

I read and also noticed the importance of using the Parameter function instead of just the parameter name

"This only takes effect when you change parameters using the Parameter function"

Thanks! This solves my issue.
