Ahhh yes, this makes sense (sorry Werner, I couldn't get this far on my
own :)
However of course things still break. Marshalling gives me:
[...]
<hash-item key="_testPricingSub4">
<value>
<costItems>
<costItem>
<currency>GBP</currency>
<amount>10.00</amount>
<exchangeRate>1</exchangeRate>
<type>price</type>
</costItem>
<costItem>
<currency>GBP</currency>
<amount>1.75</amount>
<exchangeRate>1</exchangeRate>
<type>tax</type>
</costItem>
</costItems>
<preTaxAmount>10.00</preTaxAmount>
<postTaxAmount>11.75</postTaxAmount>
<taxRate>0.175</taxRate>
</value>
</hash-item>
[...]
but passing that back to unmarshalling gives me:
1)
testQuotation(com.ingenta.ics.ecommerce.api.item.QuotationMarshallingTest)java.lang.NullPointerException
at
org.exolab.castor.xml.util.XMLFieldDescriptorImpl.hashCode(XMLFieldDescriptorImpl.java:416)
at java.util.HashMap.hash(HashMap.java:261)
I seem to see this hashCode error a fair amount; the last time I managed
to get a test case for it and reported it as a bug, but then found a
workaround. I'll try to do the same this time, but so far this time I've
been failing miserably at making my test cases break!
I'll attach the description file in case anyone can eyeball that and tell
where the problem might be. I'm rapidly losing patience with trying to
figure out where in this enormous system we have set things up poorly, so
that Castor breaks, but I don't seem to have any option but to keep
banging my head against it :P
