Hello List,

I have an order number in my EO and I need to have it be a unique number.

How can I check that my users did not type in an identical number?

I’m trying to do validation and my validation right now looks like this:

public String validateOrderNum(String value) throws NSValidation.ValidationException

{

// Check the order number is unique

NSMutableArray args = new NSMutableArray();

Args.addObject(value);

>>>>>>EOEditingContext ec = session().defaultEditingContext();

>>>>>>Project project = EOUtilities.objectWithQualifierFormat(ec, “Project”, “orderNum = %@”, args);

If(project != null)

Throw new NSValidation.ValidationException(“This number is already in use.”);

}

I keep getting “cannot find symbol” on the ec and the EOUtilities lines.

Is there a way I can get this type of validation to work?

Thanks,
