Description of problem:


    If we try to save multiple rules opened in a single tab through BRM (i.e. Guvnor) it throws the error "binaryUpToDate has been modified externally" . As per the experts the saving of each asset will try to set the 'binaryUpToDate' attribute on the package item in which these assets belong to. This is the reason why we get "binaryUpToDate has been modified externally" for the second or all the following asset saving operations.

    After this strangely, we can still see the assets are getting properly updated in BRM (i.e. Guvnor).
