Hi,
i encountered a problem with the application components feature. I created a component that should hold certain base classes. Here you will find the example: GitHub - mariodavid/cuba-example-application-components: Example for using CUBA application components
When i open the application in studio i can successfully select NamedEntity as the Superclass (for Customer class). But next time i opened up the Customer i got an error along those lines: “unmatched attribute for column ID”:
[21:04:49.484] Unexpected error
java.lang.IllegalStateException: Entity com.company.platform.projectmanagement.Customer has no attribute applicable for table id column
[21:04:49.485] Exception has been thrown by com.haulmont.studio.ui.app.a@4c5cc19f:

so i couldn’t edit it further. I created this example: GitHub - mariodavid/cuba-example-application-components: Example for using CUBA application components (where the project-management-platform project contains the MappedSuperclass and the project-management-app uses it).
Unfortunately as i just double check it before posting this, and re-clone it to another directory: Well, it does not have the error anymore (so i was able to change the superclass from Customer to NamedEntity). Then i started the app but when i want to create a customer i get the following error:
SQLIntegrityConstraintViolationException: integrity constraint violation: NOT NULL check constraint; SYS_CT_10834 table: PM_CUSTOMER column: NAME
Generally the dependency should be in included correctly, because i’ve a SayHelloService in the platform component which worked quite well.
One additional problem i encountered: When i opened the project-management-app in studio there was just the appointments dependency displayed, not the project-management-platform (although it is included as a dependency in the build.gradle file and in the web.xml files as well).
Perhaps you might want to take a look at these errors.
Bye,
Mario
