"Default Value" attribute on <g:ui_reference ??

[Makosko]

does the <g:ui_reference macro support an attribute for specifying a default value ? I can set it using a client script but that is not an ideal scenario...

the <g:ui_reference macro is to be invoked in an UI page...

Hello, I request quick favor here. How could i set dynamic value to g:ui_reference macro. To be more precise, I have checkbox field and assigned to user field, when that checkbox is enabled, assigned to user field should be cleard. But I am unable to achieve by the below code

function shardType(){

  var sh= document.getElementById("shared").checked;

  if (sh == true){

  //var temp = '';

  //document.getElementsByName("assignedto").style.visibility = "hidden";

  document.getElementById("my_substate").style.display = "block";

  document.getElementById("my_choice").style.display = "block";

  document.getElementById("my_substate").value = "--None--";

  //alert(gel('assignedto').value);

  //document.getElementById("assignedto").value="";

  //document.getElementById("assigndiv").style.display = "none";

  //document.getElementById("assignto").style.display = "none";

  //document.getElementById("assignedto").innerHTML = temp;

  //gel('assignedto').value="";

  //alert(gel('assignedto').value);

  var asn = gel('assignedto').value;

  if (asn != ''){

  alert(asn);

  document.getElementById("assignedto").value="";

  //g:ui_reference.setValue('assignedto','');

  }

The following also works with reference fields on the UI page:

<g:ui_reference name="ref" table="sys_user" displayvalue="${gs.getUser().getDisplayName()}" />
