[x3d-public] Trying to add children

[John Carlson]

I am dumping my scene:

      var xml = Browser.currentScene.toXMLString();
      document.querySelector("#x3d").innerHTML = xml;

And it only shows the ProtoBody, which is OK.

<Group>
  <Transform DEF='protoSlider'>
    <IS>
      <connect nodeField='translation' protoField='sliderTranslation'/>
    </IS>
    <Transform DEF='protoTransform'>
      <IS>
        <connect nodeField='translation' protoField='transformTranslation'/>
        <connect nodeField='translation' protoField='sensorTranslation'/>
      </IS>
      <PlaneSensor DEF='protoSensor'
          maxPosition='1 0'/>
      <Transform>
        <TouchSensor DEF='protoTS'/>
      </Transform>
      <Transform>
        <Shape>
          <Appearance>
            <Material/>
          </Appearance>
          <Text DEF='protoText'>
            <IS>
              <connect nodeField='string' protoField='textString'/>
            </IS>
            <FontStyle
                size='0.23'/>
          </Text>
        </Shape>
      </Transform>
    </Transform>
  </Transform>
  <Script DEF='protoValueTransformerScript'
      directOutput='true'
      mustEvaluate='true'>
    <field accessType='inputOutput' type='SFFloat' name='protoScale'/>
    <field accessType='inputOutput' type='MFString' name='petNames'/>
    <field accessType='inputOutput' type='SFString'
name='protoParameterName'/>
    <field accessType='inputOutput' type='SFNode' name='shader'/>
    <field accessType='inputOnly' type='SFVec3f' name='newTranslation'/>
    <field accessType='outputOnly' type='SFFloat'
name='protoValue_changed'/>
    <field accessType='outputOnly' type='MFString'
name='protoText_changed'/>
    <IS>
      <connect nodeField='protoScale' protoField='parameterScale'/>
      <connect nodeField='petNames' protoField='petNames'/>
      <connect nodeField='protoParameterName' protoField='parameterName'/>
      <connect nodeField='shader' protoField='shaderNode'/>
    </IS>
<![CDATA[../javascripts/X3DUser.js]]>
  </Script>
  <Group DEF='nodeGroup'/>
  <Group DEF='linkGroup'/>
</Group>
<ROUTE fromNode='protoSensor' fromField='translation_changed'
toNode='protoTransform' toField='set_translation'/>
<ROUTE fromNode='protoSensor' fromField='translation_changed'
toNode='protoValueTransformerScript' toField='newTranslation'/>
<ROUTE fromNode='protoValueTransformerScript' fromField='protoText_changed'
toNode='protoText' toField='set_string'/>



I am adding children nodes like:

const setMFField = function(node, fieldName, value) {
        let field = node.getField(fieldName);
        let children = field.getValue();
        children.push(value);
        field.setValue(children);
}

setMFField(nodeTransform, 'addChildren', shape);
setMFField(linkTransform, 'addChildren', shape);
setMFField(nodeGroup, 'addChildren', nodeTransform);
setMFField(linkGroup, 'addChildren', linkTransform);

Nothing is being added to the nodeGroup and linkGroup, as far as i can
tell.  The textarea is continually being refreshed.

Any hints with SAI are welcome.
