Liferay Portal 7.4 CE GA88, Liferay DXP 7.4 Update 88 bundled with the latest available version of Elasticsearch 7.x for Sidecar (7.17.12, as of Aug 7, 2023).

With this new front-end client extension users will be able to add an entry to the global import map.

This can be used to share code between decoupled client extensions that are freed from the need to know the deployment URL of the code at build time. For example, this will allow you to share your library or framework of choice among all your front-end client extensions:

For a script to consume the JavaScript module referred to by the import map entry, it needs to be of type=module.

In order to help developers to understand how to use this client extension, a sample has been provided: https://github.com/liferay/liferay-portal/tree/master/workspaces/liferay-sample-workspace/client-extensions/liferay-sample-etc-frontend-2

This new frontend client extension allows users to replace the existing theme spritemap without the need to redeploy a theme. The spritemap should include all icons needed for the scope where it is used.

The Control Panel still uses the admin spritemap.

After registering the client extension, in the page template or page you need to use it, configure it from the design options menu:

To enable this client extension, do it from the Feature Flags management UI:

This feature allows developers to create or update an object and its related elements in a single request, optimizing the requests performed to the server, thus improving the overall performance of your solution.

Provided the necessary data for the related elements (ExternalReferenceCode, Id, etc), if the element already exists, it will relate the two objects, if the related element does not exist, it will create the object and it will relate them.

It is also possible to remove related elements by just updating the parent without the elements that are not related anymore.

Now, developers will be able to filter Custom Object Entries using the field values of the related elements for a given Object entry.

It is possible to filter as many levels as needed. The format of the filter query needs to be: relationshipName1[/relationshipName(i)]*/fieldNameN. Being relationshipName1, relationshipName(i), etc the different relationship names that join Object 1 with Object i, and fieldNameN being the name of the field of the latest Object definition on which the user wants to filter.

In addition to this, our nesting capabilities have been enhanced, so now it is possible to retrieve data for an Object entry and its related elements, supporting several levels of nesting.

The names of the different relationships to retrieve need to be specified in the nestedFields parameter, separated by commas. Additionally, the nestedFieldsDepth parameter with the number of levels to retrieve needs to be specified in order to indicate to Liferay how many levels it is necessary to nest.

It has extended the support for External Reference Code to other Liferay entities in version 7.4. With this new parameter, users will be able to access, create, update and delete various entities by simply specifying the scopeKey and the external reference code.

This External Reference Code is a custom identifier, which means that at the creation time it can be set, helping to migrate entities from one environment to another while keeping this External Reference Code the same across environments. You can check the available endpoints to be accessed by External Reference Code in the API explorer.

The batch engine API allows developers to export/import data, but it requires developers to provide a configuration with multiple parameters. With the new auto-generated endpoints, it is easier to perform export operations in the portal. The export endpoints are asynchronous, so it will provide a taskId in order to retrieve/download the records requested.

The endpoints follow this format:

Now users can manage the tags and categories associated with the Objects entries from the REST APIs. When an Object has Categorization enabled, properties for tags and categories will be exposed in the Object entries schemas. Users can retrieve the information, set or update the tags and categories associated with the Object entries as well as use the information of these fields to filter information
