Hi all. I have some components being rendered in a loop. On initial
render, everything comes out fine. However, when I try to click on an
eventlink within one of the rendered components, I get an application
exception. What is going wrong here?

SearchFilterContainer.java

public class SearchFilterContainer
{
@Inject
private SearchFilterService searchFilterService;
@Property
private SearchFilter currentFilter;
public List<SearchFilter> getChronologicalSearchFilters()
{
return searchFilterService.getChronologicalFilters();
}
public String getPreFiltersText()
{
return messages.get("pre-search-filters-text");
}
public boolean isAssetStatusFilter()
{
return currentFilter.getFilterType() == SearchFilterType.ASSET_STATUS;
}
