There is small enhancement needed if the user validates dmn scenario with *collection* data type, being previously simple data type.

h2. Steps to reproduce
- Create new DMN
- Define there custom data type *LKW:string*
- Set this LKW type for some *input data* node
- Save DMN
- Create a Scenario for this DMN
- Go back to DMN
- Check tickbox *Is Collection* for the *LKW* type
- Save DMN
- Validate Scenario, you will get message as shown in the picture. It can be confusing as it says *LKW* changed to *LKW*
