Date input is supported using an <input type="text"> control.

​
Binding to a Process Variable

To bind the input field to a Java Date variable, the directive cam-variable-type="Date" must be used. Example: 
<input type="text"
       cam-variable-name="CONTRACT_START_DATE"
       cam-variable-type="Date" />

​
Date Format

Currently only the ISO Date Format yyyy-MM-dd'T'HH:mm:ss is supported. Example value: 2013-01-23T13:42:42

​
Using a Date Picker

The Form SDK itself does not provide any custom components or widgets. As such it also does not provide a date picker. However, you can integrate third party libraries providing such widgets or write one yourself (see Custom JavaScript).
Inside ASEE Flow Tasklist, datepicker support is provided through Angular UI.
You can use the Angular UI datepicker directive to offer a datepicker for the date input field. The complete markup of the input field including the datepicker button is shown below. 
<p class="input-group">

  <input type="text"
       cam-variable-name="CONTRACT_START_DATE"
       cam-variable-type="Date"
       class="form-control"
       uib-datepicker-popup="yyyy-MM-dd'T'HH:mm:ss"
       is-open="dateFieldOpened" />

  <span class="input-group-btn">
    <button type="button"
            class="btn btn-default"
            ng-click="open($event)">
      <i class="glyphicon glyphicon-calendar"></i>
    </button>
  </span>
</p>
In addition to the HTML markup, the following JavaScript must be included in the form file (see Custom JavaScript): 
<script cam-script type="text/form-script">
  $scope.open = function($event) {
    $event.preventDefault();
    $event.stopPropagation();

    $scope.dateFieldOpened = true;
  };
</script>
The attributes of the datepicker component are explained below: Additional attributes of the input element:
  • uib-datepicker-popup="yyyy-MM-dd'T'HH:mm:ss": This attribute sets the format of the date which is returned by the datepicker. It must be the ISO Date Format.
  • is-open="dateFieldOpened": This attribute contains the name of the variable, which indicates the open status of the datepicker. It must be the same variable, which is set to true in the open function in the JavaScript snippet. If a form contains multiple datepickers, they must have different values for this attribute.
Attributes of the datepicker button:
  • ng-click="open($event)": This attribute contains the name of the function which is called when the datepicker button is clicked. It must be the function name of the JavaScript snippet which sets the is-open variable to true. If a form contains multiple date pickers, they must have different function names, or the name of the is-open variable must be passed to the function.
