Hi Dan,

I like your changes. Just one problem that I have run into.

I call the DefaultTypeMappingRegistry constructor with createDefaults = true because I want to create the default mappings. Now doing that means that the typeCreator gets created in the constructor. So then when I call setConfiguration (config) on the type mapping registry, after construction, the configuration changes do NOT propagate to the typeCreator and it's nextCreator. So, i can't actually change any of the defaults!

Try this:

tr = new DefaultTypeMappingRegistry()
tr.setConfiguration(config);
tr.createDefaultMappingss();

So one solution is to allow the Configuration object to be passed into the constructor of DefaultTypeMappingRegisty. Although that still doesn't allow the user to call setConfiguration(config) after construction and have the changes propagate to the typeCreator. That would require adding setConfiguration to TypeCreator, calling it from DefaultTypeMappingRegistry.setConfiguration(config) and then implementing a chain to call setConfiguration(config) on the next TypeCreator in AbstractTypeCreator I guess.

I can do a patch for either option if you would like?

Cheers,

Adam.

I committed my version of your patch to SVN. Let me know your thoughts when you get a chance. I'm not tied to my code by any means. :-)

Hi Adam,
I've been looking at this but still have problems with the nillable stuff, but your example below breaks the semantics. You stated in your other email:

We still need the 2 different properties in order to tell what is ALLOWED to be Nillable (nullable) from what the user would LIKE to be Nillable (nillable).

But in your snippet below, you're reversing those semantics. setNullable(false) doesn't mean in that case that Date isn't allowed to be Nillable, its just what the user would like. You follow?

No... you said that Date's cannot be set to Nil="true" (even though in Java they can be set to NULL) because of a limitation of .net. So, I said that to make sure that we never output Nil="true" for Date you can set Nullable to true as below. So, the setNullable(true) is because Date's are not allowed to be Nilled, it has nothing to do with the user's wishes.

Technically this is a user preference those. Dates can be nilled, we just don't want to allow that by default if that makes more sense :-) So they're allowed, its just bad for interop.
So... to reduce confusion we should probably change the nullable property of Type.java to be called nillableAllowed.

Do you want me to do the refactoring and upload a new set of patches?

Nah, I have some other changes which I've integrated into your patch. Specifically I created a Configuration object to pass around settings (I need it for some other stuff later). Also, I removed the minOccurs from Type because minOccurs can only be set on properties of a bean.

On a related note, the patch is good and I appreciate it! I hope the debate isn't giving the wrong impression :-). I think more than anything I'm running into flaws in my design.
The real issue here is how do we know that a user hasn't overridden the nillable property on the type. For instance, say I create some custom type which I want to be nillable but set the nillable default to false. The patch will overwrite that property since there is no way to override it. Or the other way around - I set a specific type's nillability to false but set the global default to true. Once again it gets overridden.

I'm not sure there is a simple solution for this, but I'm up for ideas...

You are right, if a user creates a new type, there is no way for them to set the default value for Nillable to anything other than the System wide default for Nillable. I also don't see an easy way around this, but I also don't see it as a huge problem in the real world. Surely, the presents of a global default for Nillable is better than the not having it?

As I see it, in the real world the users probably sit in 2 camps:

1) Not bothered about highly constrained interfaces. In which case they set the global default for Nillable and MinOccurs to true and 0 respectfully and maybe use the per property overrides to add mandatory elements to their interface definition.

2) Highly constrained Interfaces are important. In which case they set global defaults for Nillable and MinOccurs to false and 1 respectfully and then use per property overrides to declare optional elements.

In either case, if they add their own user types, they probably will not deviate from case 1) or 2) and therefore the fact that they cannot set a default for their new Type that is different from the global default is neither here nor there.

Adam.

Heres what I think might be a good solution:
- Only do setNillable(isDefaultNillable()) if we are creating a new type (yours was overriding old types):

       if (newType && !getTypeConfiguration().isDefaultNillable())
           result.setNillable(false);

- Make sure that the default type mapping that is created in DefaultTypeMappingRegistry respects

protected void register(TypeMapping tm, Class class1, QName name, Type type)
   {
       if (!getTypeConfiguration().isDefaultNillable())
       {
           type.setNillable(false);
       }
             tm.register(class1, name, type);
   }

This way we're only overriding the nillable property if we explicitly want them all the be false. Which I think is the best way to do things. Either you're going to want a mix of true/false or have them all false by default. You'll never want to have them all true by default.

I wrote an additional test or two and everything seems to check out functionality wise.

Would that work for you?

Hi Dan,

Any idea when you will get a chance to integrate my updated patches?

http://jira.codehaus.org/browse/XFIRE-295?page=all

Then add:

public DateType()
{
   setNullable(false);
}

to DateType.java

Cheers,

Adam.

Hi Dan,

Ok well if dates can never be nillable then just override:

public booean isNullable()
{
   return false;
}

in DateType.java, or alternatively call:

public DateType()
{
   setNullable(false);
}

in the constructor.

This will mean that it will never come out as Nillable="true" even if the default for Nillable is true. Which it is.

Repeat for any other types that cannot be Nilled.

We still need the 2 different properties in order to tell what is ALLOWED to be Nillable (nullable) from what the user would LIKE to be Nillable (nillable).

Cheers,

Adam.
