[Vitali Yemialyanchyk]

So I'll admit it as a new JIRA issue.

That's a good use case :) 

I'd make it available for multi-selection, so it would let map not only
related classes.
It means we wold have not only reverse but also forward engineering.

Let's imagine I have several (say 10) classes that I'd like to make
persistent. The classes form completed domain model.
I decided to use hibernate and JPA annotations, I have lets say JBDS
1.1.0 or JBossTools 2.1.0 installed.
 
Question is what I should do to make my model persistent? It there
anything that helps me to do it?
    

 
Not that I'm aware, the thing that get closest is maybe Dali JPA which has
as JPA View where you can click to make something an entity.
 
I'm not sure it does anything else than add @Entity to the class.
 
  

Now I see only way. I have to go through all classes and add annotations
for class and for fields.
    

 
Having a "Make this class and its related classes mapped via JPA" would be 
an interesting Refactoring to implement.
 
Should basically just work like this:
 
makePersistent(ITypeRoot clazz, Set processed) {
  add @Entity 
  Find most likely id property and add @Id  
 
 processed.add(selectedClass);
 associations = getAssociatedClasses(selectedClass);
 
 foreach class in associations {
  if(!processed.contains(class)) {
       makePersistent(class, processed);     
  }  
}
}
 
There then might be some exceptional cases like handling version properties,
temporal values and
non-JPA supported mappings which Hibernate would be able to understand/map.

Did I miss something?

Could you define priority direction?
 
        

Fix the ones that are open for 2.1 - then we can talk future. That is what
is important now.
 
We are doing waaay to many half-solutions in the hibernate console code at
the moment. Let's
complete what we are working on instead of spawning of too many concurrent
working directions.
 
For the rest:
 
 
      

JBIDE-2008 in progress for Dima Geraskov
 
        

What is the status ?
 
 
      

JBIDE-1178 in progress for Dima Geraskov
 
        

It still has alot of bugs and thus too fragile to include in 2.1 at the
current point.
 
 
      

JBIDE-1921 Hibernate Tools User Guide - Fix Version/s: 2.2.x
 
        

Thus not for 2.1
 
 
      

JBIDE-1431 Generate Entities of non Empty Tables creates weird UIs - Fix
Version/s: 2.2.x
 
        

Yes, for 2.2.x
 
 
      

JBIDE-1708 Restore Defaults button does nothing in Properties for Hibernate
Settings - Fix Version/s: 2.2.x
 
        

 
      

-          Just admit can we start some of it?
 
        

I don't know what that means.
 
JBIDE-1708 is done.
 
 
      

JBIDE-1610 hibernate reverse engineering - Table & Columns tab -
delete/remove button - Fix Version/s: LATER
 
-          This issue should be simple and seems to be rather important to
be in 2.1.
 
        

Then suggest a fix for it.
 
 
      

JBIDE-1841 Improve error message when performing SchemaExport and an
exception occurs (e.g. SQL exception) - Fix Version/s: LATER
 
-          improve the handling of the error - also seems simple and could
be in 2.1
 
        

If you think it is simple then please suggest a way to do it. Remember
schemaexport is not the only one
throwing errors.
 
 
      

JBIDE-1913 Hibernate Code Generation - properties setup special editors -
Fix Version/s: LATER
 
-          what about this?
 
        

Yes ? Feel free.
 
 
      

JBIDE-1974 Exception occurs after add additional mapping file into Hibernate
configuration that is already listed in cfg.file. - Fix Version/s: LATER
 
-          what about this?
 
        

Yes ? Feel free to suggest a patch.
 
 
      

JBIDE-1767 & JBIDE-1768 - I can proceed with it but it seems I need your
consulting here.
 
        

Yes, so it will have to wait.
 
 
      

Could you suggest (required to do) opened suitable issues for 2.1?
 
        

There is already more than enough issues open for hibernate for 2.1 that is
still
in progress and not fixed.
 
 
      

What do you think about model creation for JBDS Hibernate - maybe it is a
time to start it? But this is not 2.1 issue.
 
        

As suggested before: come up with a way of doing it then we look at it.
 
 
      

opensource.atlassian.com - there are a lot of issues which seems to be
useful - I can dig into and propose several todo. for example
 
-          HBX-464 - add cfg.xml editor (seems the same - HBX-10  Properties
page )
 
        

 
      

-          HBX-46  allow query results to be shown lazy
 
-          HBX-895 Content assist doesn't work when an entity alias is not
preceded by whitespace
 
-          Etc. - there are a lot of propositions here - so
