Wicket LoadableDetachableModel exception handling issue

[Jayakrishnan R]

In my project, I am using LoadableDetachableModel as given below.

public ReportPage(final Objectm, final PageReference pr) throws
CustomException{try{final LoadableDetachableModel<List<MaintReport>>
ldm =
         new LoadableDetachableModel<List<MaintReport>>() {

            @Override
            protected List<MaintReport>load() {
                **// 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.
