Wicket LoadableDetachableModel exception handling issue
In my project, I am using LoadableDetachableModel as given below.
public ReportPage(final Objectm, final PageReference pr) throws
CustomException{try{final LoadableDetachableModelListMaintReport
ldm =
new LoadableDetachableModelListMaintReport() {
@Override
protected ListMaintReportload() {
**// Some Database operations //**
return x;
}
};
/*
Several LoadableDetachableModels, PageableListViews, Panels, Fragments etc.
*/ } catch ( Exception ex){// create Custom Exception } finally {
// Clean up of stuff }
My problem is that I am using AbstractColumn to display the objects in the
column and the overriden populateItem() method calls the load()
internally. Since both the methods cannot throw Exceptions, I cannot
really catch exceptions and display appropriate messages.
Any help on this is really appreciated.

Re: Wicket LoadableDetachableModel exception handling issue
How about wrapping it to a RuntimeException, or preferably, your own
subclass of it?

Re: Wicket LoadableDetachableModel exception handling issue
i have already done that as a back up plan. Do you think wicket is a bit
wierd in handling exceptions.

Re: Wicket LoadableDetachableModel exception handling issue
Actually I think Wicket offers, inherently, one of the best ways to
handle exceptions - I can catch it wherever I want, rewrap, redirect,
ignore, alter the model... I haven't seen such freedom and versatility
in any other web framework.
YMMV.
