We have an issue with NgxValidateCoreModule that emerges after it is imported to a module that has a component in which we have the following: The component is a view that has KendoTreeList in which we use kendoTreeListCellTemplate to be able to render our own custom FormControl of choice to its table cells. Kendo rows/cells have “edit mode” which means Kendo renders the form control with the form group when an editable cell or whole row is clicked. There is kendoTreeListEditTemplate for the edit mode content, but in our case, we have a custom form control that has two functionalities in one so we need to use kendoTreeListCellTemplate. This means that the content (form control) is there 100% of the time, not only in the cell’s edit mode like things are with kendo’s own editable cells. The edit mode means that when the user clicks a cell in the tree list table, it transforms to a form control with a form group. So, with the cell template with our custom form control being rendered there straight away when initing the KendoTreeList and it’s there without any surrounding form group. The control is given to it in the template definition via [formControl] directive from the the collection of form groups that represent the tree list table rows (e.g. this.formGroups[rowIndex].controls[col.field]). When we import the NgxValidateCoreModule, the following error is given <customCellTemplateWithOurFormControlCount> times:

So the questions are:

1. Is this a bug that NgxValidate requires a form group wrapper for form controls or am I missing something? Isn’t it fully legit to have form controls without a surrounding form group to begin with?
2. If this is fully intended and avoidable, how to fix this issue for our use case and ignore the required formGroup?
