Customer Portal: Upgrading Data Schemas in Development
While updating customizations for Liferay DXP, the history portlet was unable to retrieve data from the database on the table that was created by it in a previous version of Liferay (6.2 EE), and the portlet throws an error.
One thing that helped solve the issue was renaming the portlet from portlet-hbm.xml to module-hbm.xml. Not sure is this naming convention needs to be documented. It was unknown that the name of the hbm.xml file mattered since it is a configurable value.
Please review this case and update the documentation accordingly. Thank you!
