Hi Mark
Nope: the table isn't called Orders. I've started from scratch and
build 2 new tables testOrders/testUser just to issolate these objects
to rule out other relationships.
There's not much more in the error just "null null The error occurred
on line -1."
I think the problem is that CF is going into an infinite loop because
of recursive referencing (so perhaps to avoid crashing it just throws
a "null null").
To take 1 step back if you use the following XML I get this error "The
object 'Order' has a recursive link back to itself through composition
'Orders'. You will need to set one of the elements in this chain to
lazy='true' for it to work.":
<object name="User" table="testUser">
<id name="userId" type="numeric"></id>
<property name="firstName" type="string" />
<onetomany name="Orders">
<link to="Order" column="userId" />
<collection type="array"></collection>
</onetomany>
</object>
<object name="Order" table="testOrder">
<id name="orderId" type="numeric"></id>
<property name="userId" type="numeric" />
<property name="totalPrice" type="numeric" />
<property name="deliveryName" type="string" />
<manytoone name="OrderUser">
<link to="User" column="userId" />
</manytoone>
</object>
When I add lazy="true" to either the o2m or m2o the page loads fine.
I can in fact dump the none-lazy array but if I try to dump the lazy
array it throws the "null null" error - e.g. if I change the XML to
the following and try to call getOrdersArray():
<object name="User" table="testUser">
<id name="userId" type="numeric"></id>
<property name="firstName" type="string" />
<onetomany name="Orders" lazy="true">
<link to="Order" column="userId" />
<collection type="array"></collection>
</onetomany>
</object>
<object name="Order" table="testOrder">
<id name="orderId" type="numeric"></id>
<property name="userId" type="numeric" />
<property name="totalPrice" type="numeric" />
<property name="deliveryName" type="string" />
<manytoone name="OrderUser">
<link to="User" column="userId" />
</manytoone>
</object>
Cheers
Matthew
