How to safely delete a web toolkit module?

marcel.karras · March 27, 2017, 2:04pm

Hello,

I created a web toolkit module and want to remove it and all connections to it. Simple deletion of the web toolkit module directory messes things up.

Thanks in advance.

Hi,

How to remove created modules was described here: https://www.cuba-platform.com/discuss/t/how-to-remove-desktop-module-and-portlet-module-from-project

Of course, the topic is old and might be obsolete. So let me share the recipe of how to simply discover which sources should be modified.

Create a new project in CUBA Studio
Open Help → Settings and enable the Keep local history of changes option. Save settings.
Create web toolkit module.
Close the project.
In the list of projects select your project and press Show local history.
Select the commit and press Show diff

Now you can observe all the changes made by Studio during new module creation.

Regards.

Hello Rostislav,

thanks for sharing your insights. I tried the steps you’ve described, properly removed all the lines listed in the diff tool and tried to open the manually modified project. The result:

The project will show up in CUBA Studio and the build process succeeds:

What I did between creating the web toolkit module and removing it manually:

extended the login screen
created a complete custom main window layout screen following this guide
created a custom theme following this guide
added a Javascript component without Generic UI integration

I of course did a backup of my unmodified project but I guess several problems might come together here. I’d like to investigate what went wrong. Do you have any hints? Thanks in advance!
