Hi,
when the Params interceptor populates my entity beans, it must be
setting the member variables directly without using the setters.
Is there a way to tell it to use the setters? There is some logic in
the setters which it would be good if it executed.
Hi Adam,
It gives precedence to the setters. Why would it not be able to see
or set the property?
Really? That's good to know - any work-around was looking distinctly
horrific.
These are JPA pojos, so the setters should be available.
Maybe it's breaking the javabean spec in some subtle way - I
double-checked the memvar, getter, setter and constructor though and
it looks OK.
Could it be the way I am using converters?
I set up a converter to instantiate an entity bean, rather than doing
it in the ModelDriven interceptor. Could that force OGNL to set its
fields directly rather than using its setters?
I'm not sure. I ran into this same issue recently and cursed at lot at
OGNL only to find out it was caused by erasure of the generic type (ie.
the class of the setters argument was Object, not what I thought). It's
worth debugging this with a breakpoint. The OGNL implementation is
quite straight-forward in the way it searches for
properties/methods/members matching the right signature. As it loops
through all the properties you should see why it missed the one it
should have set.
Doing that now - hopefully the answer will point to a simple solution. I can
already see that Hibernate has got its grubby nose in there.
