[Kogito - VSCode] Validation of DMN file: How to Enforce Data Type Consistency in Input Values?

[kanetran]

In my DMN file in VSCode, I have defined specific data types for each object.

For example, volume is defined as a number. However, I noticed that it is still possible to enter values of different types (e.g., strings or other unexpected inputs).

I need to validate that the input values strictly match the defined data type. The validation should occur in one of the following cases:

• When a user enters the value in VSCode.
• When the rule is saved in VSCode.

I using:

• DMN version version 1.2.
• Java version 17.
• Kogito API version 10.0.0

I am looking for ways to enforce this validation effectively. Is there a built-in way in DMN to enforce type consistency?

Any guidance or best practices would be greatly appreciated!

This should be doable using our https://marketplace.visualstudio.com/items?itemName=kie-group.extended-services-vscode-extension . However, we need to recheck this scenario as there were recently updates to this extension, that are not publicly available yet.

I see, but in some cases, it seems that the validation does not catch errors correctly. For instance, I have a volume field of type number, but when I write a rule with a text value like "abc", it does not detect the error.

It would be great if this scenario could be rechecked to ensure proper validation. Looking forward to any updates on this!

I understand, I am using the extension built locally from main branch. I was able to see an error about using string instead of number:

Yes, I see it work for DMN 1.5 and extended-services-vscode-extension 10.0

For any reason like test scenario,.. I can not upgrade to DMN 1.5.

In my previous example, I was using DMN 1.2 with Kogito Extension 10.0 (extended-services-vscode-extension 10.0).

As far as I can see, the extended-services-vscode-extension version 10.0 only works with DMN 1.5, while the Kogito Bundle 0.32.0 is for DMN 1.2. However, I couldn't find the extended-services-vscode-extension when I downgraded to version 0.32.0.

Well, I am sorry for this situation with incompatible versions. We are approaching merge of the new scesim-editor, that will be compatible with DMN 1.5

Thank you for your support! I'm also looking forward to DMN 1.5 being able to run test scenarios as soon as possible.
