> Endless recursion if LoadableDetachableModel.load throws exception

> Key: WICKET-3302
> URL: https://issues.apache.org/jira/browse/WICKET-3302
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5-M3
> Reporter: Willis Blackburn
> Assignee: Igor Vaynberg
>
> I don't know if there's any easy fix for this, but here's what happens:
> 1. Component subclass overrides isVisible with a new implementation that
> depends on the current model state.
> 2. The model is a LoadableDetachableModel.
> 3. On the initial render, the load method of the LoadableDetachableModel
> throws a RuntimeException for whatever reason. (In my case I was trying to
> throw a AbortWithHttpErrorCodeException.)
> 4. This gets caught in Component.getDefaultModelObject:
> log.error("Error while getting default model object for Component: " +
> this.toString(true));
> 5. The toString method that's invoked from the exception handler prints the
> component's state, including its visibility.
> 6. In order to resolve the visibility state, toString has to call
> isVisible--the same method that initially caused the exception.
> 7. The isVisible method again throws an exception, etc.
