Button click to change from Calculated Read Only to Calculated User Can Override

[#1]

I want to change a bunch of checkboxes from Calculated Read Only to Calculated User Can Override via JavaScript button click.

Would greatly appreciate input!

I have figured out that I really don't require the checkbox to be Calculated - User Can Override status. Now I've added an app.alert on the Click Event that displays my required message.

Thank you for the response.

It seems like if the field has already had a user entered value then setting the calculate override warning doesn't have any effect.  If you execute your code before the user enters a value then it seems to work.

If you wrap the checkbox in a subform with a repeat and an min occurrence of zero and initial occurrence of one, you could remove the checkbox, then re-add it and then set the calculate override warning.

If CheckBox1 is set to "Read Only" or "Protected" I am able to unlock it with this click event in Button1:

oTargetField = this.resolveNode("CheckBox1");

     oTargetField.access = "open";

But, unfortunately, I need to change it to Calculated - User Can Override.

I tried this to no avail:

oTargetField = this.resolveNode("CheckBox1");

     oTargetField.calculate.override = "warning";
