At the moment it is not possible to open and edit dataset in modal dialog if the dataset is not in correct state, e.g. if all mandatory fields are not filled. The CloseAndCommit requires that there are no errors. There are situation where there’s need to do a partial modification of the dataset in a modal dialog while the main screen is responsible for final validation.
We suggest the introduction of a new close type CloseAndCommitWithErrors, which will allow merging data from the modal dialog even if case of incomplete data in the underlying dataset.
