Hello,

I think there are several ways of achieving it, and one of them could be overriding the page provider used to retrieve the documents inside a folder. If you check the Web UI request while loading the page, you will see the page provider used is advanced_document_content.

So you only need to override it. Information about the page provider: https://explorer.nuxeo.com/nuxeo/site/distribution/server-10.10/viewContribution/org.nuxeo.ecm.document.pageproviders–providers

You need to scroll to the “advanced_document_content” page provider definition and copy it in your own contribution. As you can see, there is a property called “sort” at the end, property that you have to modify like follows:

<sort ascending="true" column="dc:title"/>

You also need to remember that you are overriding an existing page provider, so you need to include the following requirement to your component in order to be sure it will be loaded after the default page providers are loaded:

<require>org.nuxeo.ecm.document.pageproviders</require>

I have tested this solution and it worked as expected. Below you can find the full code. Hope it helps!

Full code:

    <require>org.nuxeo.ecm.document.pageproviders</require>
