Problem Description:
When trying to serialize an ORM entity to Json, a NullPointerException is thrown in specific situations.
To test, I have an extremely simple database with the following tables:
Delivery -> Package <-> PackageOrder -> Order
Delivery:
id
Package:
id
deliveryId
PackageOrder:
orderId
packageId
Order:
id
The Order entity has an extra field computed at runtime (persistent="false") with a custom getter:
property name="hashid" type="string" setter="false" persistent="false";
public string function getHashid(){
return "COMPUTED" & variables.id;
}
When using the following code, the crash happens:
public any function getObjectToSerialize(){
var delivery = entityLoadByPK("Delivery", 1);
var obj = delivery.getPackages()[1].getPackagedOrders()[1].getOrder();
return obj;
}
// Somewhere else:
try{
WriteDump(var=serializeJSON(getObjectToSerialize()), abort=true); // NullPointerException
}catch(any e){
WriteDump(var=e, abort=true);
}
Dumping the entity returned by getObjectToSerialize is working as intended.
The stack is available in the notes below.
Interestingly, deleting the custom getHashid getter will prevent the error from happening.
Steps to Reproduce:
Use the application in the attached zip.
Actual Result:
NullPointerException
Expected Result:
A Json representation of the entity
Any Workarounds:
N/A
