Steps to Reproduce:
1. Start up a clean 7.2 bundle
2. Go to Control Panel > Web Content and create folder "workflow"
3. Edit the workflow folder and apply the single approval workflow
4. Go to Control Panel > Workflow > Process Builder
5. Click on Single approver workflow
6. Select review node and click notification
7. Paste the below script into the template textbox:
<#assign journalArticleLocalService = serviceLocator.findService("com.liferay.journal.service.JournalArticleLocalService") /> <#assign articleId = serviceContext.getAttribute("articleId") /> <#assign article = journalArticleLocalService.getArticle(groupId?number, articleId) /> <#assign title = article.getTitle() /> ${userName} sent you a document ${title}.
8. Start up POSTMAN https://www.postman.com/downloads/
9. Change URL from GET to POST --> http://localhost:8080/o/headless-delivery/v1.0/structured-content-folders/39308/structured-contents
10. Replace 39308 with your workflow folderid (I got the value from the journalfolder table)
11. Go to Authorization tab and change type to Basic Auth and enter Test Test credentials
12. Go to Body tab and copy paste the following:
{
"actions": {
},
"availableLanguages": [
"en-US"
],
"contentFields": [
{
"contentFieldValue": {
"data": "<p>new sample content </p>"
},
"dataType": "html",
"label": "content",
"name": "content",
"nestedContentFields": [],
"repeatable": false
}
],
"contentStructureId": 38858,
"customFields": [
],
"friendlyUrlPath": "new-sample-content",
"siteId": 20124,
"subscribed": false,
"title": "new sample content"
}
13. Change contentStructureId to the Basic Web Content Structure found in DDMStructure
14. Send POSTMAN request
15. Go to User Profile > Notifications and approve the content
16. In Postman change URL to PUT --> http://localhost:8080/o/headless-delivery/v1.0/structured-contents/34376
17. Replace 34376 with your journalarticle resourcePrimKey
18. Go to Body tab and copy paste the following:
{
"actions": {
},
"availableLanguages": [
"en-US"
],
"contentFields": [
{
"contentFieldValue": {
"data": "<p>new sample content </p>"
},
"dataType": "html",
"label": "content",
"name": "content",
"nestedContentFields": [],
"repeatable": false
}
],
"contentStructureId": 38858,
"customFields": [
],
"friendlyUrlPath": "new-sample-content",
"siteId": 20124,
"subscribed": false,
"title": "new sample content"
}
19. Send POSTMAN request
Expected Behavior: Request completes without errors
Actual Behavior: Request completes but ServiceContext attribute for articleId is blank
