Possible problem with bean-deployer_2_0.xsd

[dmlloyd]

IDEA does not like .xml files that use a namespace attached to the bean-deployer schema (since the extraction of the jboss-beans-common stuff into a separate file I suspect). And the IDEA folks say that it's an XSD problem, as other validation tools come to the same conclusion.

The problem is that elements within top-level "bean" elements are all marked invalid. The errors reported are as follows:

/home/david/src/java/microcontainer/trunk/kernel/src/main/resources/schema/bean-deployer_2_0.xsd
 Error:Error:line (139)rcase-RecurseLax.2: There is not a complete functional mapping between the particles.
 Error:Error:line (139)src-redefine.6.2.2: Group 'valueGroup' does not properly restrict the group it redefines; constraint violated: 'rcase-RecurseLax.2'.

Note that the error location is in the XSD file, not the jboss-beans.xml file that I'm actually validating.

Is this our problem or theirs?

[dmlloyd]

By the way, validating it (second-hand via my contact at JetBrains) with another tool produces marginally more useful output:

SystemID: D:\LloydsXSD\bean-deployer_2_0.xsd
Location: 139:36
Description: rcase-RecurseLax.2: There is not a complete functional mapping
between the particles.

I don't read alienese and the error messages aren't very helpful.

But I'd guess from this link (see the table) that you are not allowed to
derive a choice from a choice except under very specific circumstances?
http://www.w3.org/TR/xmlschema-1/#cos-particle-restrict

If that's true, its kind of stupid since both choice groups are identical. ;-)

But the obvious fix would be to not redefine the choice group and just
specify it explicitly in bean-deployer-2.0.xsd.

Its exactly the same definition so we aren't actually gaining anything
from the redefine that I can see?

From that link:

One of the following must be true:
2.2.1 {particles} is empty and the particle within which this <choice> appears has {min occurs} of 0.
2.2.2 All of the following must be true:
2.2.2.1 The particle within which this <choice> appears has {max occurs} and {min occurs} of 1.
...

This isn't true for baseCollectionType which has an unbounded choice

 <xsd:complexType name="baseCollectionType">

 <xsd:choice minOccurs="0" maxOccurs="unbounded">

 <xsd:group ref="valueGroup"/>

 </xsd:choice>

...

In any case this doesn't look like the source of the IDEA problem after all (they're still researching it though)...

[dmlloyd]

Ah, they found the issue. It's a bug in IDEA, and it has been fixed in their recent 8.0.1 release. Hooray

and it has been fixed in their recent 8.0.1 release. Hooray

It works like a charm. Finally! :-)

Same problem for Eclipse 3.4.2/WebTools 3.0.4 (which uses Xerces 2.9.0 for validation as far as I know).

Any plans to change something on the JBoss side? I don't know whether the error message is correct or not.

Thanks

I commented on the errors some time ago here
http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223327
If it's still not fixed it should be.

The validation error is also in JIRA as part of https://jira.jboss.org/jira/browse/JBMICROCONT-446
