How to programmatically set Channel Localized Metadata attributes

Hi. I am trying to programmatically set an attribute of Channel Localized Metadata. But I cannot manage to get it to work.

I have tried a few different ways. Here is the basic example.

Assuming I have a channel, I do:

ChannelData data = channel.getData();
ChannelLocalizedData localizedData = data.getLocalizedData(locale);
ContentInstance locMetaData = localizedData.getDescriptor();
AttributeData attr = locMetaData.getAttribute("MY_ATTRIBUTE");
String myValue = (String) attr.getValue();

That is all working fine. I can read the attribute from Localized Metadata. But now I want to change the attribute.

I have tried this:

locMetaData.setAttributeValue("MY_ATTRIBUTE","My Value");
locMetaData.commit();

When I do that I get an exception: Error 13 (MOCommitError), Message 026-133-0009: A content item cannot be moved to the root folder.

I also tried like this:

locMetaData.setAttributeValue("MY_ATTRIBUTE","My Value");
channel.commit();

But that does not cause the attribute to be changed.

Does anyone know how to do this?

The Metadata and Localized Metadata are stored as the xml representation of a content instance, therefore your should never commit such content instances !

To set the metadata/localized metadata just use the setDescriptor method:

ChannelData data = channel.getData();
ChannelLocalizedData localizedData = data.getLocalizedData(locale);

ContentInstance descriptor = localizedData.getDescriptor();
descriptor.setAttributeValue("MY_ATTRIBUTE", “hello world”);
localizedData.setDescriptor(descriptor);

//and now you have to commit the channel !

channel.commit();

ciao

Hi Mario. Thanks.

I have tried that:

ContentInstance descriptor = localizedData.getDescriptor();
descriptor.setAttributeValue("MY_ATTRIBUTE", “hello world”);
localizedData.setDescriptor(descriptor);
channel.commit();

I've even tried editing the XML directly using:

String xml = localizedData.getDescriptorXml();
// manipulate xml
localizedData.setDescriptorXml(xml);
channel.commit();

The channel shows the correct modified date as if the update happened, but nothing is changed in the Localized Metadata. I have spent hours at this point and cannot get anything to change. I'm starting to think there is a bug or regression or something. I am working with 8.5.1 with the latest cumulative patch 20141124.

Ok, let me give it a try and get back to you

Hi Mario. Thanks.

I have tried that:

ContentInstance descriptor = localizedData.getDescriptor();
descriptor.setAttributeValue("MY_ATTRIBUTE", “hello world”);
localizedData.setDescriptor(descriptor);

I wrote this sample standalone java code which is able to succesfully set the Channel Localized Metadata for the Innovate site.

-------------------------------------------------------------- class TestLocalizedData ---------------------------------------------------------

package com.vignette.vps;

import com.vignette.as.client.common.ChannelData;

import com.vignette.as.client.common.ChannelLocalizedData;

import com.vignette.as.client.common.ref.AsLocaleRef;

import com.vignette.as.client.javabean.Channel;

import com.vignette.as.client.javabean.ContentInstance;

import com.vignette.as.client.javabean.ContentType;

import com.vignette.as.client.javabean.Site;

import com.vignette.config.client.appserver.AppServerClient;

import com.vignette.util.GUID;

import java.util.Date;

import java.util.Locale;

public class TestLocalizedData {

public static void main(String[] args) throws Throwable {

String host = "localhost"; //set your VCM hostname

int port = 7021; //set your VCM port

String user = "vgnadmin";

String pwd = "vignette";

//login to VCM

new AppServerClient(host, port, user, pwd) ;

//Use the Home channel of the Innovate Site for our test

Site site = Site.findByName("Innovate");

Channel channel = site.getHomeChannel();

ChannelData channelData = channel.getData();

AsLocaleRef asLocaleRef = new AsLocaleRef(Locale.getDefault());

ContentType ctLocalizedMetadata = (ContentType)ContentType.findByName("INNOVATE_CHANNEL_LOCALIZED_METADATA");

if(channelData.getLocalizedData(asLocaleRef) == null){

ChannelLocalizedData channelLocalizedData = new ChannelLocalizedData();

channelLocalizedData.setLocale(asLocaleRef);

ContentInstance descriptor = (ContentInstance)ctLocalizedMetadata.newInstance();

descriptor.setAttributeValue("ID", GUID.generateString());

descriptor.setAttributeValue("summary", "Created at "+ new Date());

channelLocalizedData.setDescriptor(descriptor);

channelData.addLocalizedData(channelLocalizedData);

} else {

ChannelLocalizedData[] channelLocalizedDataArray = channelData.getLocalizedData();

for(ChannelLocalizedData channelLocalizedData: channelLocalizedDataArray) {

if(asLocaleRef.equals(channelLocalizedData.getLocale())){

ContentInstance descriptor = channelLocalizedData.getDescriptor();

if(descriptor == null) {

descriptor = (ContentInstance)ctLocalizedMetadata.newInstance();

}

System.out.println("summary = " + descriptor.getAttributeValue("summary"));

descriptor.setAttributeValue("ID", GUID.generateString());

descriptor.setAttributeValue("summary","Created at "+ new Date());

channelLocalizedData.setDescriptor(descriptor);

}

channelData.setLocalizedData(channelLocalizedDataArray);

}

channel.commit();

ChannelLocalizedData channelLocalizedData = channelData.getLocalizedData(new AsLocaleRef(Locale.getDefault()));

ContentInstance descriptor = channelLocalizedData.getDescriptor();

System.out.println("summary = " + descriptor.getAttributeValue("summary"));

}

Mario, thank you so much. Your code does work. It took me a while to figure out what the secret was that I was missing. Here is what I was doing originally:

ContentInstance descriptor = localizedData.getDescriptor();
descriptor.setAttributeValue("MY_ATTRIBUTE", “hello world”);
localizedData.setDescriptor(descriptor);
channel.commit();

Here is what you have to add to get the changes to take effect:

ContentInstance descriptor = localizedData.getDescriptor();
descriptor.setAttributeValue("MY_ATTRIBUTE", “hello world”);
localizedData.setDescriptor(descriptor);
--> channelData.setLocalizedData(channelLocalizedDataArray);
channel.commit();

I guess you basically have to replace the entire localizedDataArray if you are altering one of the ChannelLocalizedData elements in the array. Not very intuitive for me, but thank you again so much. Now my code is working.

Mario_DAnna

That’s correct, you perfectly got the point.
