Anonymous beans

[dmlloyd]

In my deployment, I want to be able to programmatically build a BeanMetaData, which represents a bean that should be injected into the property of another bean.

However I hit a problem that I probably won't be able to explain properly, but here goes:

First of all, the container is giving an error if the nested bean doesn't have a name. I don't see why it needs a name though, since it's only referenced by the outer bean?

Second, the nested bean doesn't appear on the deployment, so even if the nested bean has a name, the deployment still fails with a "CONTEXTS MISSING DEPENDENCIES" message.

Basically I'm trying to programmatically replicate this kind of structure:

<bean name="TheOuterBean" class="...">
 <property name="prop">
 <bean class="some.inner.Bean"/>
 </property>
</bean>

Am I making any sense?

Your are probably looking for this:

It even has the same subject name. :-)

I need to check why the programmatic approach doesn't work.
Can you create me a test case out of your work?

Or check AbstractBeanMetaData.getBeans / NestedBeanHandler, that's where the nested bean logic is.

Well, the error message I'm getting is completely different, and I'm working with a programmatic deployment rather than an XML deployment, so it looks like a completely different problem to me...

...OK, it seems entirely possible that I'm just doing it wrong. I'm instantiating a BeanMetaDataBuilder for the nested bean, using the getBeanMetaData() to get it, and then just directly adding that resulting bean to a parent builder via the builder.addPropertyMetaData("prop", nestedBeanMetaData) method.

I'll look at those classes and see where my error is.

What's your error?

That should work.
XML transformation doesn't do anything different than what you do programmatically.

And that's exactly what I'm doing in my test:

For some reason I felt inspired to completely restructure my metadata last night at about 1:00am. Once I get back to this point, I'll post more info. Unless of course it decides to just work. :-)
