Hi,

Please try following example,

<textbox id="tbx" constraint="no empty"/>
<button label="clear">
  <attribute name="onClick">
      tbx.setRawValue(null);
      tbx.clearErrorMessage();    //hide 'no empty' warning
  </attribute>
</button>

Note that after clearing the textbox, its value will be ""(an empty string) but null.
