When I try to define the following mappings, I get a NullPointer exception:
<binding add-constructors="true" direction="output">
<mapping abstract="true"
class="org.regenstrief.queryposer.QueryCutpointAdapter">
<value name="name" get-method="getName" style="attribute"
usage="optional"/>
<value name="ordinal" field="ordinal" style="attribute"/>
</mapping>
<mapping name="cutpoint"
class="org.regenstrief.queryposer.QueryCutpointText"
extends="org.regenstrief.queryposer.QueryCutpointAdapter">
<structure field="operand"/>
</mapping>
<mapping name="cutpoint"
class="org.regenstrief.queryposer.QueryCutpointConcept"
extends="org.regenstrief.queryposer.QueryCutpointAdapter">
<structure field="operand"/>
</mapping>
</binding>
I have a parent QueryCutpointAdapter object and different cutpoint types
as children. Text and Concept cutpoints have a different xml form. I
understand that for unmarshalling, there probably needs to be unique
element names. However, since I have explicitly declared my direction as
output only in the binding definition, shouldn't I be able to marshal
objects with the same element names as long as repeated element names
each point to a unique object type? If not, how can I serialize my xml
with the above object structure?
Thanks,
Tammy
