Hi,
I have a table which has the following structure.
currency varchar2(4),
amount1 double,
amount2 double

My Object model looks something like below
class Something {
Amount amount1;
Amount amount2;
}

class Amount {
String currency;
double amount;
}

I would like to map the single column currency to each amount field.
my hbm looks something like below
<component name="amount1" type="Amount">
<property name="currency" column="currency">
<property name="amount" column="amount1">
<component>
<component name="amount2" type="Amount">
<property name="currency" column="currency" insert="false" update="false">
<property name="amount" column="amount1">
<component>

Though the schemaexport utility works fine with this, at run time I get a mapping exception.
Any help would be greatly appreciated.

Thanks

Use:

<component name="amount1" type="Amount">
<property name="currency" column="currency">
<property name="amount" column="amount1">
<component>
<component name="amount2" type="Amount" insert="false" update="false">
<property name="currency" column="currency">
<property name="amount" column="amount1">
<component>

Hi Gavin,
Firstly THANKS A LOT !! for this extremely prompt reply. I truly apologise for the mistake in the code posted. The hbm fragment should read as below... i.e the component amount2 is presisted as amount2 column. The currency field is common.

<component name="amount1" type="Amount">
<property name="currency" column="currency">
<property name="amount" column="amount1">
<component>
<component name="amount2" type="Amount">
<property name="currency" column="currency" insert="false" update="false">
<property name="amount" column="amount2">
<component>

I truly apologise for wasting your time.

Thanks again.

Ah, so currently, and for the forseeable future, some mapping attributes do not apply to properties of a component. The insert and update attributes are like this. Unfortunately, this would be very difficult to change.

and how can i solve this problem with xdoclet. xdoclet have one attribute [code]class
and [b]not [/b][/code]name?
