ISSUE
When opening or running a Nintex Task Form, the following error might occur:The form is referencing a field that does not exist. Please notify the form designer.
ERROR CODE
The form is referencing a field that does not exist. Please notify the form designer.RESOLUTION
- Use Runtime Function "isNullOrEmpty" to check the value of "TaskOutcome". For instance: isNullOrEmpty(TaskOutcome).
- Make sure the "TaskOutcome" control has a default value If "isNullOrEmpty" does not apply.
- When the field "Default value source" in "Task Outcome" choice control setting has been set to "Specify default value", make sure that "Default value" is not blank/empty.
The end user can populate this with double quotes/speech marks and space i.e (" ")
This is based on the business requirement of not having any value set on the outcome. - Ensure that when using a workflow variable that is connected to a control, if the variable name is changed you must re-bind the variable to control.
ADDITIONAL INFORMATION
There are more than one possibility as the root cause of the issue:- This issue occurs because one of the Rules that is using 'Task Outcome' is empty or does not have the default value.
- This issue occurs because the Task Outcome control configuration of: 'Specify default value' > 'Default value' is set to blank / with no value.
- If a workflow variable connected to a control is renamed or deleted, and the form control’s “Connected to” is not updated to account for the change, the form will generate the error listed.
