----------------------------------------
Hi Jacopo,
Was just reading your comment by chance. Yes this makes sense to me. Maybe
that's the reason why Leon forgot it, Leon ?
> Leaving out rel-field-name in keymap causes NPE
> -----------------------------------------------
>
> Key: OFBIZ-1187
> URL: https://issues.apache.org/jira/browse/OFBIZ-1187
> Project: OFBiz
> Issue Type: Bug
> Components: order
> Affects Versions: SVN trunk
> Reporter: Leon Torres
> Fix For: SVN trunk
>
>
> If you leave out the rel-field-name for a keymap that requires it,
> DatabaseUtil.java will crash with a NPE when trying to create it.
> To reproduce, add the following to an entityengine.xml,
> <extend-entity entity-name="OrderAdjustment">
> <field name="orderAdjustmentSubTypeId" type="id"/>
> <relation type="one" fk-name="ORDER_ADJ_SUBTYPE"
> rel-entity-name="OrderAdjustmentType">
> <key-map field-name="orderAdjustmentSubTypeId" />
> </relation>
> </extend-entity>
> Note that the <key-map> is missing a rel-field-name="orderAdjustmentTypeId".
> Do an ant run-install to create the key. It should crash with a NPE
> pointing to line 2150 in DatabaseUtil.java:
> ModelField relField =
> relModelEntity.getField(keyMap.getRelFieldName());
> I believe it should be testing that getRelFieldName() is null, and if so then
> log a warning and skip the key.
