Re: Locatable UnsupportedOperationException

2020-05-30 Thread Sven Meier 

Hi,

just put a breakpoint on IModel#setObject().

Once your problem hits that breakpoint, you'll be able to derive the 
offending component/model from the stacktrace/variables in your favorite 
IDE.


Have fun
Sven

During the process of throwing an exception, the Java Virtual Machine
abruptly completes, one by one, any expressions, statements, method and
constructor invocations, initializers, and field initialization expressions
that have begun but not completed execution in the current thread. This
process continues until a handler is found that indicates that it handles
that particular exception by naming the class of the exception or a
superclass of the class of the exception (§11.2 <
https://docs.oracle.com/javase/specs/jls/se11/html/jls-11.html#jls-11.2>).
If no such handler is found, then the exception may be handled by one of a
hierarchy of uncaught exception handlers (§11.3 <
https://docs.oracle.com/javase/specs/jls/se11/html/jls-11.html#jls-11.3>)
- thus every effort is made to avoid letting an exception go unhandled.

Yes , but it may contains deep-nested model

The form contains FormComponentPanel and contains another
FormComponentPanels and widgets , very deep ...
The error may lay under very deep model , which is very hard to debug.
And the error message should be able to pinpoint which model causes the
problem

Yes , I know...
But I hope it will be more informative.
Because in practice , there may be lots of models , nested panels , forms
, even in one page...
Informative error message can make us quickly understand which model needs
to implement setObject.
(just like the un-serializable field error message)

Hi,

Depending on the model you use, you may need to ovveride the setObject() method.

from the API docs

default void setObject​(T object)

Throws:
UnsupportedOperationException - unless overridden

Locatable UnsupportedOperationException

2020-05-30 Thread smallufo 
Hi
I am building an app with complicated forms , nested models ...
Some times it obsesses me is the UnsupportedOperationException :

java.lang.UnsupportedOperationException: Override this method to support
setObject(Object)

at org.apache.wicket.model.IModel.setObject(IModel.java:84)
It doesn't pinpoint me which model , which form , which panel...
very hard to debug...
For non-serializable exception , it can provide meaning information , even
pinpoint which field causes the problem.
I hope some day , this UnsupportedOperationException can also be so
informative.

Thanks.
