When I have used spaces in the Correlation property name, it caused issue number 2 and 3 (may be 4 also) in this https://github.com/sartography/spiff-arena/issues/1764
And when I used a apostrophe it caused issue number 9 there.
For the message name we have said that no spaces and special characters are allowed. But for the correlation property name no such message is shown, so I assumed I can use spaces there.
And we are not validating the user inputs for the message name/correlation property name/retrieval expression.
I think we should validate it and if there is an issue which what the user has entered we shouldn't allow to save it.
