David E. Jones commented on OFBIZ-1399:
---------------------------------------
There are certainly lots of little things that can be done to improve the user
experience.
In this case if a user didn't understand that they were creating a link between
the catalog and the category, then a message saying that the category didn't
exist wouldn't make any sense to the user.
There's no way around it: for generic user interfaces like most of those in
OFBiz you have to know a bit about what you are doing in order to get things
done.
It is certainly possible to create user interfaces that guide the user through
a process, but you have to have the process defined first! For most processes
automated with OFBiz that means narrowing down to a certain role and operation
that is part of a coordinated set of roles for a certain type of organization.
If you only have one organization to worry about this is easy, but for OFBiz in
general we don't have that luxury, so it's hard to get that sort of efficient
UI into the project.
This is the dilemma that we face... There are more specific solutions for
certain roles and processes in the specialpurpose components, but in the
general application components we are trying to keep things pretty generic in
order to avoid huge confusion due to a large number of custom UIs that are
irrelevant or bad practices for various user organizations.
