Symptoms
Rules on Form now not visible in K2 Designer since upgrade to 4.6.10
Diagnoses
This issue occurs after upgrading the environment from 4.6.7 to 4.6.10. You then see smartform rules going missing, and you are not able to amend it. In runtime mode the complete rule goes completely missing.
Also further errors appear when trying to package the project as well, making this hard to deploy to another environment.
Resolution
The rules in question will have to be reconfigured again to the views as well as the smart objects having to be remapped to the rules that are missing here.
Once this has been done no further errors should appear within smartforms or P and D.
