I using SQL Developer Data Modeler Version Version 220.127.116.113 to create a new database structure based in an existing schema.
I have imported the schema with reverse engeneering add the new entities and relationships(FK) and for a few months everything works perfect.
Now I want to make some modifications in the ER Model but I am not able to open the property window of some(not all) of the entities and is not shown any error message.
Meanwhile I have installed the version 18.104.22.1684, but the problem persists.
Have any errors been logged to the log file?
This is normally file datamodeler.log in folder datamodeler\datamodeler\log (unless its location has been changed on the Environment/Log page of the Preferences).
