1.1 Issue with the Confirm Version to Check Out dialog box

When checking out an artifact from ClearCase®, you may be presented with a dialog box asking if you want to check out the latest version in order to prevent the need for a future merge. This happens because someone else has already checked in a newer version of the artifact based on the same ancestor version as yours. It is absolutely necessary that you answer "no" to this suggestion. Answering "yes" will immediately create a situation in which your model, which will usually consist of multiple physical artifacts (model files or fragment files) will be made up of inconsistent parts. This can easily lead to model corruption. In the case of a fragment in the middle of a model (i.e. that has child fragments), entire branches of the model can be corrupted. The relationship between fragment files is actually tighter, with a higher level of mutual dependency, than that between models that reference each others' elements. Thus, extreme care must be used when checking out from ClearCase.

Note that this affects you only if you are sharing a stream with other users. If you have a view on a private UCM development stream, then your view will always be synchronized and you will never see this dialog box.

If you accept this request, you must immediately update your entire view and synchronize the whole model again.
