Inform User that he provided a duplicate Condition During Experimental Group Creation

[Steffengreiner]

What are you missing?

During Experimental Group creation, if the user provides the same experimental group condition multiple times, only one experimental group is created without informing the user that a duplicate group was provided.

Why do you need a solution?

While this is technically correct, it can confuse the user why the other group was not created.
Additionally the reason is provided within the log but not shown to the user necessetating manual intervention:

life.qbic.projectmanagement.application.experiment.ExperimentInformationService Could not create experimental group, response code was CONDITION_EXISTS

Ideas

Ideally a solution that shows the user the duplicate experimental group within the dialog before closing would be preferred similiar to how it is done in the experimental variable update.

There are two underlying requirements here:

• Req 1: The app must ensure unambitious conditions for experimental groups within an experiment.
• Req 2: The app shall inform users about condition duplicates upon experimental group creation.

I need to check if Req 1 is ensured.
