Re: [jibx-users] Does recursion works? Failure on unmarshalling.

I've used recursive structures without a problem. From the error message it looks like you've got an <Expression> element in the XML, which is not defined by the binding. What's your actual XML document?

Hi,

I'd like to implement a flexible configuration which uses JiBX to configure 
somewhat flexible expressions.
It uses a recursiive definition for an expression. Compilation of the binding 
works well but
on unmarshalling, a failure is detected:

Does anybody have a hint what is going wrong?
Does anybody successfully used recursion?


Many thanks for any
hint,

First, I have defined:

 <mapping class="com.macd.xConnect.gateway.snmp.management.lang.Expression"
          abstract="true" />

 <mapping name="And"
          class="com.macd.xConnect.gateway.snmp.management.lang.And"
          extends="com.macd.xConnect.gateway.snmp.management.lang.Expression">

   <collection field="expressionList"
               
item-type="com.macd.xConnect.gateway.snmp.management.lang.Expression"
               usage="required"/>
 </mapping>

 <mapping name="Or"
          class="com.macd.xConnect.gateway.snmp.management.lang.Or"
          extends="com.macd.xConnect.gateway.snmp.management.lang.Expression">

   <collection field="expressionList"
               
item-type="com.macd.xConnect.gateway.snmp.management.lang.Expression"
               usage="required"/>
 </mapping>

 <mapping name="FunctionDefinition"
          
class="com.macd.xConnect.gateway.snmp.management.lang.FunctionDefinition">

   <value style="attribute" name="name" field="name" usage="required" 
ident="def"/>
   <structure field="argumentDefinitionList" usage="required"/>
   <structure field="expression"             usage="required"/>
 </mapping>


and some other elements. The JIbX binding is created well:
