In K2 Designer, when you use a combination of properties from different SmartObjects from the “Recent” node in the context browser an error occurs. This also causes an error in K2 Package and Deployment when deploying a workflow created with this issue.
The following errors occur in K2 Workflow Designer:
Console error #1 when dragging from “Recent”: “Uncaught TypeError: Cannot read property 'methods' of undefined”
Console error #2 when dragging from “Recent”: “Uncaught TypeError: Cannot read property 'length' of undefined”
The following error occurs in K2 Package and Deployment:
Error when deploying: “Missing reference at SmartObjectField . Error: The best overloaded method match for 'string.IsNullOrEmpty(string)' has some invalid arguments.”
When a Recent item is dragged over, the last cached SmartObject is used.
- Ensure you have K2 (5.1) installed.
- Get the K2 Five (5.1) FP1 from Regional Support.
- Install the K2 Five (5.1) FP1 to apply the fix.
It is recommended to refresh the browser cache.
