[rules-users] Merge repository in Guvnor and editing brl with eclipse plugin

[ioda100]

Hi,

I try to figure out how to import a package from an instance of guvnor to
another instance of guvnor without destroying all the existing repository.

There is an import/export function in the administration part of guvnor but
it export all the repository and when import a repository, it's erasing all
before importing.

What i would like to be able to do is : i have a package with rules,
functions, enum, dsl, test scenarios... under an instance of guvnor and i
have another package under another instance and i would like to import the
second package to the other instance of guvnor without erasing the existing
repository. Is it a way to do this? i can't find it. maybe with the eclipse
plugin? I don't want to import from a drl file because i would loose the
graphical part (use of dsl, enum...).


My second question is that i try to use the guvnor plugin for eclipse to
manage rules in the guvnor repository. I can access to it and read/modify
all but i can't modify the ".brl" files, i get for all the files this
message : "Could not open the editor: An unexpected exception was thrown.
