Tips & Tricks

In some cases, when updating the Entity Domain Model (model.edm), incompatible changes may occur. To resolve these issues, here are some Tips & Tricks about it:

1. Delete the generated files:
   • Delete all files under the "e-learning" project except model.edm, model.model and project.json
2. Unpublish the e-learning project
3. Re-generated the application from the updated model.model
4. Publish the e-learning project

In most cases, the previous steps should be enough to resolve issues from an incompatible change in the model. However, if incompatible change in the Data layer is made (e.g. Null -> Not Null, VARCHAR -> INTEGER, ...) then one addition step should be executed first:

1. Go to the Database perspective
2. Find the database table(s), to which incompatible changes were made
3. Right click on it
4. Select Drop Table from the menu

Otherwise execute SQL queries, to drop the table(s), from the SQL view:

drop table STUDENTS

In some cases the generated application view(s) may disappear or be closed by accident. To reset the default layout follow these steps:

1. Click on the "Themese" menu
2. Select the "Reset" option
