CSLoadSelectedArticle fails to invoke PreDisplayArticleExtension
After upgrading to Pega Knowledge 8.4 application, the CSLoadSelectedArticle activity fails to invoke the customized PreDisplayArticleExtension activity.
Steps to Reproduce
- Upgrade to Pega Knowledge 8.4 application from Pega Knowledge 7.4.
- Customize PreDisplayArticleExtension activity.
- Log in to the application.
- Click an article in the Knowledge Base.
In Pega Knowledge 7.4 application, the PreDisplayArticleExtension activity is customized. The CSLoadSelectedArticle activity invokes PreDisplayArticleExtension, but contains no when condition. In Pega Knowledge 8.4 application, the when condition is added in Customer Service layer for supporting out-of-the-box use cases. The when condition is also added in CSLoadSelectedArticle, which invokes PreDisplayArticleExtension. However, the when condition fails and the extension properties are also not set causing the issue in Pega Knowledge 8.4.
Apply HFix-64638. BUG-578164 resolves the issue in Pega Knowledge 8.5 release.
