Module or extension name already exists while updating Forge Component
Question

Dear all,

just started with a lot updates of Forge Components.
Often I get the message "Module or extension name already exists" and I'm not able to continue.
Obviously the message is correct, but it's concerning a existing module of the application to be updated.
Sometimes I just delete the old one, and install the new version, but this is not always possible, for example if the component also has a DB entity, which is already filled.

Any idea how to fix this? And why suddenly these messages appear (while updating components)?

Also a second question/discussion.
When I use a Forge Component which is consuming OutSystems UI, and OutSystems UI is updated, then this Forge Component automaticly will be a custom version (also indicated when trying to update this component).
Should the owners of this component always create a new version, consuming the new OutSystems UI?

Best regards,

Jeroen Vormer

Hi @Jeroen Vormer 

It’s generally best to follow a clear naming convention for application modules in your environment. For example, add a prefix at the beginning of the module name, such as AL_, MYAPP_, or any company/project-specific initials like XX_.

This way, each module will always have a unique name, and you’ll avoid conflicts when installing or updating components from Forge. When you download a new Forge component, you can also rename the modules accordingly before integrating them.

Hope this helps!

regards,

@Manish Jawla ,
Probably you misunderstood my question!
I'm updating a Forge Component, which contains obviously the same module-name as I already have!
Then I receive this message/error.
Best regards,

I had several. From my mind for example 'Ultimate PDF' and 'BDDFramework'.

No log present regarding this message.
I'm using the "Forge Updates" feature from Service Studio, and the messages appears in the Forge itself.

One more thing, take a look at this. You might be upgrading from a traditional system to a reactive one.

Indeed if you select "Install anyway" you'll receive this error.
