Description

There is a regression in a Sequence diagram that a [New] button to add Operation for Messages gets disabled by following the step below:

1. Click a Message in a Sequence Diagram.
2. [New] button in the [Operation] field is active if the message doesn’t have any Operation been set.
3. Open the drop-down list and choose “Unspecified”.
4. [New] button is disabled even it is in the same condition – the operation is “unspecified”.

Workaround

Release the Message and select it again will make the [New] button active again.

Will fix in the next update which we plan in this Fall.
