[ http://jira.codehaus.org/browse/JIBX-100?page=all ]
Dennis Sosnoski updated JIBX-100:
---------------------------------
Priority: Minor (was: Major)
The problem occurs because Outer doesn't extend Middle and Middle doesn't
extend Inner. If the classes *were* in this relationship this would be a valid
binding; because they're not, the binding is invalid (it's saying to treat the
Outer instance as a Middle instance within the first <structure>, then to treat
it as an Inner instance within the second <structure> - that's what a
<structure> with a type but no property means). I've added checks to the code
to catch this type of binding error.
> nested structures: Expected jibxproblem.Inner on stack, found
> jibxproblem.Middle

> Key: JIBX-100
> URL: http://jira.codehaus.org/browse/JIBX-100
> Project: JiBX
> Type: Bug
> Components: core
> Versions: JiBX 1.0.1
> Environment: Windows XP
> java -version
> java version "1.5.0_05"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
> Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)

> I have posted the problem already on jibx-user, but there was no traffic wrt
> to this entry.
> I am not sure whether JIBX-98 is the same problem. At list it looks a little
> bit different.
> Starting last week with jibx I got to some strange problems
> java.lang.IllegalStateException: Internal error: Expected
> jibxproblem.Inner on stack, found jibxproblem.Middle
> (see stack below)
> May be I made some simple beginners error, but I could reduce to two extremly
> simple nested structures(*):
> <binding>
> <mapping name="Outer" class="jibxproblem.Outer" >
> <structure name="Middle" type="jibxproblem.Middle" >
> <structure name="Inner" type="jibxproblem.Inner" >
> <value name="myInnerId" style="attribute" field="myInnerId" />
> </structure>
> </structure>
> </mapping>
> </binding>
> (*) Originally I started with a complex binding with nested collections with
> items factored into separate mappings
> again with nested collections partly in base classes.
> As I got first problems with the mappings I moved to structures and
> collections inside the root mapping.
> manfred
> btw: the attachment contains the correspondig example classes compilation is
> possible simply by javac *.java
