NotAllowedError: removeField action on button mouse-up

Question

Is this.removeField or something else in the below script a trusted function?

I'm trying to create a button that will delete fields by type. I want the button to delete buttons, checkboxes, and radio buttons.

I already have this as an action and it works, but I'd like it as a button for easy access and for other users to use.

I'm getting the following error: NotAllowedError: Security settings prevent access to this property or method. Doc.removeField:11:AcroForm:MouseUp:Action1

Below is the script I've modified from another forum, but can't seem to find the link to reference. The only difference is I added the or operand to find multiple field types. It's set to a mouse-up event. I've also tried putting most of it document level except for the last for condition and the delete button action., but that still produces the error. Additionally, I tried this.removeField with a named field and it works. I guess I'm not seeing anything that would require a trusted function...

//Remove Buttons and Checkboxes
var fields = new Array();
for ( var i=0; i<this.numFields; i++) 
{
var fname = this.getNthFieldName(i);
if ((this.getField(fname).type == "button" || this.getField(fname).type == "checkbox" || this.getField(fname).type == "radiobutton"))
 {
 fields.push(fname);
 }
}
for (var i=0; i<fields.length; i++)
{
this.removeField(fields);
}

I'm running Acrobat Pro DC.It's strange that the code works in an Acrobat Action but seems to produce an error when ran via mouse-up.There are several fields with the same name for text field duplication and to keep the file lighter and less complicated.On a side note, I was under the impression that Reader DC no longer needed usage rights enabled...Not for saving filled-in forms, but it does require it for executing some JS commands.So this is happening when you run the code in Acrobat, from a button? Could it be that you're trying to delete the button that triggered this code? That would be a problem, as it's still being used at that moment.

I used the same code (this.removeField(fields);) in my Javascript which was attached to a Button, and yes I was removing that same Button. In Adobe Acrobat Pro 9 my Javascript worked fine; that Button was removed. However when I upgraded to Pro DC then I got that same error message. For the last week I was trying to figure out how I could change my security settings to eliminate that error.

When I read this post I realized I did not have to remove the Button field, just make them hidden. My goal is to flatten all the form fields and eliminate all the Button fields. When I changed the code to f.display = display.hidden;, my Javascript worked in Pro DC. Once I flattened the document the Button fields were completely gone.

I still think there must be a way to change the security settings so that I could remove the field with Javascript. It still works fine in Acrobat 9 Pro. This is why I have some hesitation when it comes to upgrading.

I hope that my other Javascripts will continue to work without and debugging.
