1) Why have we completely change the Web GUI and disregard the role
of "Business" End user" loving Guvnor 5.5 in favor of something which
is a kind of interface for "Developer" ?
It is already accepted that the Project Explorer in 6.0 is a poor substitute for the Asset Viewer in 5.5. A new "Navigator" for 6.0.Final is on the table.
2) Why have we removed a lot of the features/functionality's proposed by Guvnor 5.5 in Guvnor 6.x (import POJO ....) ?
Guvnor 6.0 follows the changes made to Drools Expert 6.0. The previous concept of what constituted a "package" has changed completely.
This had led to a change in how POJO models need to be uploaded: previously they just had to be on the classpath at build-/run-time; now they need to be declared as a project dependency and uploaded to a repository.
There is a whole new API for 6.0 for developers using Drools Expert 6.0 too.
With kind regards,
Mike
