We have 3 environment (dev, tst, prod).
Every K2 component has a version number, the designer shows it. But if I move a package to another environment with package and deployment tool the version number change (base on targeted environment). E.g. a smarform has ver.5 in dev will be ver.1 on prod.
There should be a solution where the version numbers are the same. Unfortunatelly there is no metadata the view/smartform/workflow where we add own version number.
