Re: [mdt-papyrus.dev] Plugin No-Singleton in Papyrus

Hi Benoit

I could just imagine a *.doc plugin being non-singleton to allow multi-version viewing, but even that might have ripples. Anything else must be a bug.

Hi,

 

Here is the list of plugins that aren’t singleton in Papyrus main [1]

Also the extract from OSGI norm for singleton [2]

 

IMHO: We should only have singleton in Papyrus.

Is there any use case in Papyrus context where no-singleton plugin may be interesting?

Is there a reason for these plugins not having the singleton=true parameter?

 

Regards,

Benoît

singleton - Indicates that the bundle can only have a single version resolved in an environment.

A value of true indicates that the bundle is a singleton bundle. The default value is false. The

Framework must resolve at most one bundle when multiple versions of a singleton bundle with

the same symbolic name are installed. Singleton bundles do not affect the resolution of non-singleton

bundles with the same symbolic name.
