Multifield value is not coming in page

Can you try adding the composite="{Boolean}true" property to the multifield? A composite multilfield can handle multiple fields within a field set.

Sharing as an example:

<states
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/foundation/form/multifield"
    class="full-width"
    fieldDescription="Click '+' to add a new page"
    fieldLabel="Sites"
    composite="{Boolean}true">

This post [0] explains well!

Consider the following dialog XML:

@dipu2 

Use @ChildResource Annotation to get all the multifield values using sightly.

Example: 

@ChildResource

private List<Resource>installationdocmtlink;

Please let me know if you need any help with this.

Hi Nupur and All,

After I changed in field , also value is not coming in my page.

The issue is here either I put @childresource "or" @Optional , multifield value is not coming. Am I missing anything in java class ?

Please help me.

Hi @dipu2,

In the Model class originally shared in post has the adaptables -> SlingHttpServletRequest.class alone. 

In the second trial it has both request and resource.

Either ways, below will work. 

Explanation :

With respect to the component resource that is adapted to the Model (that we write), multifield node is a child resource/node.

Hence we need to use this annotation(@ChildResource) with type as "Resource".

In the HTL, now the getter exposed is of type "Resource" and hence listChildren on the same would work.

(I assumed that you have tried this annotation with String data type and @Via("resource") per the commented code)

@Via is needed only when the object other than original adaptable is needed. You can even try removing @Via("resource") in "header" dialog field. It should still work. 

Please update this thread if you still face any issues. 

Note :

Given the available list of annotations(considering the adaptables), we have few other ways of retrieving values authored via multifield component. With the code shared, we can use this as an option. Will try to cover other possibilities in some time. 

Hi Vijaya and All,

Hi Vijaya,

I tried by putting below code in model , as suggested by you.

protected static final Logger LOGGER = LoggerFactory.getLogger(InstallationDocumentImpl.class);

@ValueMapValue
@2434638("resource")
private String header;

// Inject the installationdocmtlink node under the current node

/*
* @586265
*
* @7392697 public Resource installationdocmtlink;
*/

@ChildResource
private Resource installationdocmtlink;

public static String getResourceType() {
return RESOURCE_TYPE;
}

@9944223
public String getHeader() {
LOGGER.info("Before return header *******" + header);
return header;
}

@9944223
public Resource getInstallationdocmtlink() {
LOGGER.info("Before return12345" + installationdocmtlink);
return installationdocmtlink;
}

@9944223
public String getExportedType() {
return RESOURCE_TYPE;
}

}

But still it is not working and in my logfile , I am getting below null for multifield.

Soon I am posting my whole package in github and share the link with you.

Dear Vijaya and All,

I tried by putting below code in model , as suggested by you.

protected static final Logger LOGGER = LoggerFactory.getLogger(InstallationDocumentImpl.class);

@ValueMapValue
@Via("resource")
private String header;

// Inject the installationdocmtlink node under the current node

/*
* @inject
*
* @Optional public Resource installationdocmtlink;
*/

@ChildResource
private Resource installationdocmtlink;

public static String getResourceType() {
return RESOURCE_TYPE;
}

@Override
public String getHeader() {
LOGGER.info("Before return header *******" + header);
return header;
}

@Override
public Resource getInstallationdocmtlink() {
LOGGER.info("Before return12345" + installationdocmtlink);
return installationdocmtlink;
}

@Override
public String getExportedType() {
return RESOURCE_TYPE;
}

}

But still it is not working and in my logfile , I am getting below null for multifield.

2020-07-28 06:38:09.962 INFO [com.sunita.core.components.internal.models.v1.InstallationDocumentImpl] Before return header *******installation

Please find my component and java files. NOTE that now I am focusing more on the getting dialog multi field values in slingmodel through logger rather than HTML.

It is stopping me for releasing sprint. Please help me.
