I had to fix the issue Error: [ng:cpws] Can't copy! Making copies of Window or Scope instances is not supported. http://errors.angularjs.org/1.6.3/ng/cpws in order to use angular-formly with angularjs 1.7.8 (it was a pentest requirement to use the latest version of angularjs) . What I did is to replace the function reverseDeepMerge(dest) . So far it seems to have solved it.
function reverseDeepMerge(dest) {
      _angularFix2['default'].forEach(arguments, function (src, index) {
        if (!index) {
        _angularFix2['default'].forEach(src, function (val, prop) {
          if (!_angularFix2['default'].isDefined(dest[prop])) {
              //dest[prop] = _angularFix2['default'].copy(val);
              if(typeof val === 'object' && val!==null){
                  dest[prop] = Object.assign(Object.create(val.__proto__),val);
                  dest[prop] = val;

          } else if (objAndSameType(dest[prop], val)) {
            reverseDeepMerge(dest[prop], val);
      return dest;

Hello! I have created a custom component to support inline editing in ngx-datatable. (https://stackblitz.com/edit/angular-ivy-qk3thq). It is working fine when I am using an online IDE. But when I try implementing the same in local, the editable fields are not rendering and values of the form-fields are displayed. Can anyone help me on this issue?

Dear formly community. I really like formly. It has saved a lot of time for me. I have started a new open-source project where end-users can build and save their formly templates interactively. I call it "data-template-form" . https://github.com/cviolbarbosa/data-template-form. I would love to have suggestions of how to improve the library, its usability and request for features. Thank you.
