Default Value of Field with variables – Symphonix

You can set the default value of a field as a variable. Use default value including $variable with care.

Should not create a dependency cycle
If you are not sure whether the dependent $variable is available before the evaluation, do not use this feature. For example, you should not have $this.attr(…) as the default value since when a record data is read from the backend, the value order is not guaranteed.
Recommended best practice: only use $global and $currentStage in the default value expression.
