Nested Multifield in Content Fragment - AEM 6.5 ?

Avatar

Level 6

I have implemented  multi-field  in content fragment and it working and there is no any issue.

Also, Implementing nested multi-field but somehow it is working but not working fully. Values are getting save at backend but when i open the content fragment there are no auto value rendering in CF.

Has anyone implemented it or written JS code for the same . Please let me know. Thank You..!!

I have tried this once and had to do a lot of customization to get it working.

In your content fragment model, you need to make the change similar to this: ( i am just showing a part of CFM which I had made composite multifield.

<multifieldtest
	jcr:primaryType="nt:unstructured"
	sling:resourceType="granite/ui/components/coral/foundation/form/multifield"
	composite="{Boolean}true"
	fieldLabel="Test Service"
	listOrder="1"
	maxlength="255"
	metaType="text-single"
	name="testSection"
	renderReadOnly="false"
	showEmptyInReadOnly="true"
	valueType="string[]">
	<field
		jcr:primaryType="nt:unstructured"
		sling:resourceType="granite/ui/components/coral/foundation/container"
		name="./testSection">
		<items jcr:primaryType="nt:unstructured">
			<column
				jcr:primaryType="nt:unstructured"
				sling:resourceType="granite/ui/components/coral/foundation/container">
				<items jcr:primaryType="nt:unstructured">
					<!-- your fields go heare -->
				</items>
			</column>
		</items>
	</field>
</multifieldtest>

After that, used the following code to populate the data into the fields:

(function ($) {
    var CFM = window.Dam.CFM,
        MASTER = "master",
        CFM_EDITOR_SEL = ".content-fragment-editor",
        CORAL_MF_ITEM = "coral-multifield-item",
        EAEM_COMPOSITE_ITEM_VALUE = "data-eaem-composite-item-value",
        MF_NAME_ATTR = "data-granite-coral-multifield-name",
        COMPOSITE_MF_SEL = "[data-granite-coral-multifield-composite]";

    CFM.Core.registerReadyHandler(getMultifieldsContent);

    extendRequestSave();

    function getMultifieldsContent(){
        if(!compositeMutifieldsExist()){
            return;
        }

        var url = CFM.EditSession.fragment.urlBase + "/jcr:content/data.2.json";

        $.ajax(url).done(loadContentIntoMultiFields);
    }

    function loadContentIntoMultiFields(data){
        var $composites = $(COMPOSITE_MF_SEL), mfValArr, mfAddEle,
            vData = data[getVariation()], $lastItem;

        if(_.isEmpty(vData)){
            return;
        }

        _.each($composites, function(mField){
            mfValArr = vData[getNameDotSlashRemoved(($(mField)).attr(MF_NAME_ATTR))];

                return;

            _.each(mfValArr, function(mfMap){

                $lastItem = $(mField).find(CORAL_MF_ITEM).last();
                $lastItem.attr(EAEM_COMPOSITE_ITEM_VALUE, mfMap);
                Coral.commons.ready($lastItem[0], function (lastItem) {

        if(_.isEmpty(mfMap)){

        mfMap = JSON.parse(mfMap);

        _.each(mfMap, function(fValue, fKey){
            const field = mfItem.querySelector("[name$='" + fKey + "']");

@Asutosh_Jena_ Thanks Ashutosh for reply. Multifield i have already implemented in CF. I am looking for nested multifield in content fragment that is somehow working but not fully. For that we need to write the custom js code, I need that. Thanks

While closing browser tab of authored Content Fragment without making any changes, losing the value from content fragment. I am using 6.5.16 AEM version, I had downgrade AEM version 6.5.7 but same issue. Followed same implementation as you suggest. Can you check once from your side @kchaurasiya

@Kishore_Kumar_ Thanks Kishor. I have already implemented multifield in component but  I need to implement in Content Fragment not in component. Thanks

Oh ok my bad sorry. I haven't tried customizing CF for nested multifield capability in 6.5. But if you can share us some sample code what you have achieved so far, me/someone may help to fix.

This is what you can try:

  • Add a content reference multifield in the first content fragment model.
  • Create a 2nd content fragment model and again add a multifield of required type there.
  • Reference the content fragments of second type from the first type

I think this would be the simpliest way to achieve this. May me you can try customizing as given in the links shared here in previous comments depending on your requirement.

@prashantonkar : Thanks for reply. I have tested multi-field the same way and it is working as expected in the Content Fragment.

 

But my question is related to nested-multi field.I think the code that you shared it seems its for multifield.

JS code that you shared so is it for multifield or nested-multifield???

 

Thank You.

Hi @bgatya789654532120

I had the same issue. 
The root cause of this issue is from the block code of the file 
/libs/dam/cfm/admin/clientlibs/v2/adminpage/editsession.js

 

    $(window).on("beforeunload", function() {
        if (isTestingMode) {
            return undefined;
        }
        if ((isActive && ns.EditSession.isDirty()) || ns.RequestManager.hasPendingRequests()) {
            if (window.Dam.CFM.EditSession.isDirty()) {
                saveLastModifiedInfo();
            }
            jQuery(document).trigger(window.Dam.CFM.constants.EVENT_CONTENT_FRAGMENT_BLOCK, {
                unloadHandling: true
            });
            window.Dam.CFM.editor.Page.notifyNavigation();
        }
        return undefined;
    });

 

My workaround is to disable the beforeunload event is fired when the current window, contained document, and associated resources are about to be unloaded.
by inserting the block code below inside the mutifield js file. 

 

    disableContentFragmentAutoSave();

    function disableContentFragmentAutoSave() {
        $(window).off("beforeunload");
    }

 

 Hope it's useful to you.
Thanks

Instead of using the following sling:resourceType , 

sling:resourceType
granite/ui/components/coral/foundation/form/multifield
granite/ui/components/foundation/form/multifield


use the resourceType : dam/cfm/admin/components/authoring/contenteditor/cfmmultifield
