[ http://jira.codehaus.org/browse/XFIRE-705?page=comments#action_80106 ]
Pascal Lalonde commented on XFIRE-705:
--------------------------------------
The source of the NPE is that the InterfaceInvocationHandler doesn't have all
bean properties in it, because they were not specified into the Request. So the
readProperty method is returning null.
This happens on server side, when the service is getting the arguments, has
proxy objects, but implementing my interfaces. So when calling the
getMinimumPriceRange of my object (But the instance is a proxy object
implementing this interface). Somewhere, it ends in the
InterfaceInvocationHandler, and the invoke methods is returning null.
I do understand why, but I can't avoid the NPE, so I need to do the following
everywhere:
[...]
int priceRange = 0;
try{
int priceRange = foo.getMinimumPriceRange();
} catch(NullPointerException npe){
priceRange = -1;
}
[...]
I'm not sure if this is clear enough.
