instanceof problem with JSField

Classic Servoy

Hi all, I’m having a problem indentifying the instance of a component. JSField are not detected.

var _formComponents = _jsForm.getComponents();
for (var k = 1; k <= _formComponents.length; k++) {
   /** @type {JSLabel|JSField} */
   var _jsComponent = _formComponents[k - 1];
   var _elementType = null;
   if (_jsComponent instanceof JSField) {
      _elementType = _bandElement.CONSTANTS.bandElementTypes.TEXT_FIELD;
   } else if (_jsComponent instanceof JSLabel) {
      _elementType = _bandElement.CONSTANTS.bandElementTypes.STATIC_TEXT;
   }
   application.output(_elementType); // JSField returns null. Running with debugger you can see that the instanceof JSField condition never applies
}

I’m using Servoy 7.4.0 - build 2026

Same here. JSField components are not detected as instance of JSField. For buttons and labels it works fine.
I was wondering if we have any option to get class name or constructor name of any object.
