I've been trying to create webcontent articles programmatically in liferay 7.3.5. I've succeeded in creating and updating them but adding a display page template hasn't been succesful. I use the method add-article from the JournalArticleServiceImpl class. This method says you can add a layoutUUID. But this doesn't seem to work.

So what i've been trying to do is using the method in javascript (add-article from journalarticleserviceimpl). In this method i give it a groupId, a folderId, a titlemap and description map, content in the form of xml and a ddm structure and template key. When retrieving a webcontent article that has a display page template, the layoutUUID is shown in the api/jsonws. Adding this same UUID to my method however doesn't actually do anything.

Here's my javascript attempt so far

Liferay.Service('/journal.journalarticle/add-article', {
groupId: 590594,
folderId: 591144,
 titleMap: {"nl_NL":" " + NLTitle + " ", "en_US":" " + ENTitle + " ", "uk_UA":" " + UKTitle + " "},
descriptionMap: {"nl_NL":" " + NLOmschrijving + " ", "en_US":" " + ENOmschrijving + " ", "uk_UA":" " + UKOmschrijving + " "},

},

Does anyone know of another method of doing this? Either in java or javascript
