Case 1

1. Select Features and open new wizard for Option Set
2. Unselect the Option 2 radio
3. Click on Save button

BUG - Option 2 radio gets selected again after the saving.

4. Click on Option 2 again -
   BUG - Option 2 remains selected and subheader is not correct now, option 2 is duplicated

Case 2
This case is reproducing when Option 2 contains occurrences of htmlArea inputs, for example

  <option name="option_2">
          <label>Option 2</label>
          <default>true</default>
          <items>
            <input name="htmlarea_2_4" type="HtmlArea">
              <label>HTML content 2:4</label>
              <occurrences minimum="2" maximum="4"/>
            </input>
          </items>
        </option>

Unselect the Option 2 and save the content

BUG- 500 error appears after saving the content

5:05:34.323 ERROR c.e.x.j.i.e.JsonExceptionMapper - NullPointerException
