Simulink System Composer Dictionary Create Constraints

I am creating a dictionary from scratch using systemcomposer.createDictionary but get following error messages.

Violated uniqueness constraint.

Error in Simulink.dictionary.archdata.create

Error in systemcomposer.createDictionary

Hi @Melih,

I tried to reproduce this error but I couldn't. I tried having a duplicate dictionary name and a duplicate file name that is not a dictionary. Are you able to readily reproduce this? Can you share the source material with us?

Hi Melih,

From what I understand, you are trying to create a dictionary by following the following syntax:

>>systemcomposer.createDictionary(“file_directory/dict_name.sldd”);

It is possible that there already exists a dictionary which was created with the same name. Try executing the following command:

>>Simulink.data.dictionary.closeAll

This will close all connections to open data dictionaries created previously. Alternatively, you could try closing a connection of a specific dictionary using:

>>Simulink.data.dictionary.closeAll(“file_directory/dict_name.sldd”)

After that retry creating the dictionary.

Hopefully, this resolves your error.
