Abstract
A computer-implemented method for preventing reference invalidation when reversing operations in synchronous collaborative applications may include (i) storing, on a client, a shared model of an engineering object including one or more features, (ii) receiving, from a user, an operation to be performed on the feature, (iii) before performing the operation, storing, in a command stack on the client, information sufficient to restore the feature to a state prior to performing the operation, (iv) receiving, from the user, a request to reverse the operation, (v) determining whether reversing the operation will create an invalid reference due to a conflicting operation having been performed on the feature at a second client, and (vi) in response to determining whether reversing the operation will create an invalid reference, reversing the operation or performing a resolution operation to prevent the reference invalidation. A system corresponding to the above method is also disclosed.
