Oliver Heger updated CONFIGURATION-271:
---------------------------------------
Priority: Minor (was: Major)
Fix Version/s: (was: 1.5)
1.6
Assignee: (was: Emmanuel Bourg)
Issue Type: New Feature (was: Bug)
So far all our configurations have bag semantics, i.e. a value can occur
multiple times for a single property.
If I understand this ticket correctly, you basically want to introduce set
semantics, i.e. the values of a single property are unique. It should be
possible to switch between the different modes.
I think, this is a good idea and certainly makes sense for certain use cases.
However, implementing this feature in a clean way won't be a trivial task.
Multiple configuration base classes will be affected. Because of that we
probably won't be able to get this into the next release. So I am setting the
fix version to 1.6
> BaseConfiguration duplicates multi value keys values

> Issue Type: New Feature
> Affects Versions: 1.4
> Reporter: Daniel Adrian
> Priority: Minor
> Fix For: 1.6
>
>
> In addPropertyDirect(String key, Object value) the method adds the new value
> to the property.
> If the property has the same value in the list, it will get duplicated.
> The method should check if the list contains the value and only if the result
> is false add the value.
> There is no logic in saving a multi value key with more than one instance of
> a value.
