TypeError: Cannot read property '$$notifyModelModifiedStateChanged' of null

Hi!

I have some legacy system and I got a problem with this midule. There is the form

<form novalidate name="studyDesignDetailForm" ng-init="initializeForm()" class="form-horizontal"
                  role="form" data-disable-all="readOnly">
    <label>Label_1</label>
    <input name="sDesignName" type="text" maxlength="255" ng-model="studyDesign.studyDesignName"
           class="form-control input-sm" ng-readonly="!isStudyActive"/>

    <label>Label_2</label>
    <input type="text" name="overdueDays" class="form-control input-sm"
           ng-pattern="numericPattern"
           onkeypress='return event.charCode >= 48 && event.charCode <= 57' maxlength="4"
           ng-model="currentTimePoint.overdueDays "
           ng-disabled="currentTimePoint.scheduled=='N'?true:false" ng-required="currentTimePoint.scheduled=='N'?false:true && !readOnly"/>
</form>

For 2nd input I get exception:

TypeError: Cannot read property '$$notifyModelModifiedStateChanged' of null
    at angular-input-modified.js:386
    at angular.js:19612
    at completeOutstandingRequest (angular.js:5964)
    at angular.js:6243

'cause when ngInputModified's ngModel directive is executing the form in null. In ngModelModifiedFactory

  // Handling controllers.
  var modelCtrl = controllers[0];    // ModelController
  var formCtrl = controllers[1];     // null
  var bsModifiable = controllers[2]; // null

Do you have any idea what's go wrong?

From the top of my head:

1. Why are you using ng-init to initialize the form? Can't you do this right away in the controller? If you need to resolve something - it's good idea to do it in router's resolve.
2. If you need to show the form conditionally, consider hiding it inside of ng-if to prevent directives from execution until the form is ready or abstract it away to it's own directive.
