ResolveNodes doesn't find all nodes

Question

Hi there,
I would like to find all text fields with a specific name in my form (and do things with them...).
Funny thing is: I sometimes get only one hit or no hits at all. I never managed to get the correct whole list of fields. Am I doing something wrong?
My code is (here in the form-ready event):
var arrayFields = xfa.resolveNodes("myField[*]");
if (arrayFields == null) {
    xfa.host.messageBox("nothing found");
else {
    xfa.host.messageBox(String("Number of Fields found: " + arrayFields.length));
    for (var iFieldCounter = 0; iFieldCounter < arrayFields.length; iFieldCounter++) {
        xfa.host.messageBox( arrayFields.item(iFieldCounter).somExpression);
    } // for iFieldCounter
} // else some result
PS. I have a little sample form ready. Yet I don't find a way to upload it to the forum.

As resolveNodes has an issue with returning objects located in subforms below $template.#subform.#subform[*], you're left with traversing the dom tree yourself.
Thanks for that information. Saved me from trying things for ever.
I wrote this function "resolveNodesFixed()" instead. Whoever has the same problem in the future may try it this way:
var arrayFields = resolveNodesFixed("myField");
if (arrayFields == null) {
    xfa.host.messageBox("nothing found");
else {
    xfa.host.messageBox(String("Number of Fields found: " + arrayFields.length));
    for (var iFieldCounter = 0; iFieldCounter < arrayFields.length; iFieldCounter++) {
        xfa.host.messageBox( arrayFields[iFieldCounter].somExpression);
    } // for iFieldCounter
} // else some result
function resolveNodesFixed(sObjectName) {
    // Finds all objects by the name of sObjectName starting from the top.
    // Parameters:
    //        sObjectName: Name of the searched for object
    // Result:
    //         returns an array of found objects. It may be empty.
    arrayHits = new Array();
    traverseForm(xfa.form, arrayHits, sObjectName);
    return arrayHits;
} // function resolveNodesFixed()
function traverseForm(oFormNode, arrayHits, sObjectName) {
    // runs thru all nodes of the form and adds every node with the name "sObjectName" to arrayHits
    // Parameters:
    //        oFormNode:   starting node. From this node downwards this function searches for nodes.
    //        arrayHits:   array to add the found nodes to
    //        sObjectName: Name of the searched for object
    // Result:
    //         returns true if everything is all right
    try {
        //xfa.host.messageBox(oFormNode.somExpression + " - " + oFormNode.nodes.length);
        for (var iIndexChildObject = 0; iIndexChildObject < oFormNode.nodes.length; ++iIndexChildObject) {
            var oChild = oFormNode.nodes.item(iIndexChildObject);
            if (oChild.name == sObjectName) {
                arrayHits.push(oChild);
            }  // if oChild.className == sObjectName
            if (oChild.isContainer) {
                // this node appears to be a subform. Recursivly we check this subform's sub nodes.
                traverseForm(oChild, arrayHits, sObjectName); // if the node contains subnodes make a recursive call to the function
            } // if oChild.isContainer
        } // for iIndexChildObject
    } // try
    catch (e) {
      console.println("Error: " + e);
      return false;
    } // catch
    return true;
} // function traverseForm()
