Hi,

I would like to have constraint for an attribute. Datatype for that attribute is custom Enum type.

How to implement ocl constraints such that message is displayed when a particular value is selected from the drop down.

Thanks and Regards,
Swathi

Hi Swathi

What you write makes no sense.

Why should a constraint be evaluated when you select from a pull-down?

The pill-down is meta-model driven so only shows sensible values.

More complex validation waits until you hit Validate.
