[RESOLVIDO] VRaptor, só é possível receber Boolean de checkboxes?

Gostaria de saber se só é possível receber Boolean de checkboxes no vraptor.

Por exemplo:

<input type="checkbox" name="webSiteCategories[0]" value="${category1Id} />
<input type="checkbox" name="webSiteCategories[1]" value="${category2Id} />
<input type="checkbox" name="webSiteCategories[2]" value="${category3Id} />
<input type="checkbox" name="webSiteCategories[3]" value="${category4Id} />

O que eu estava esperando é receber uma Lista de Longs List dos checkboxes marcados.
Mas a lista está vindo null, e no LOG do VRaptor aparece isso:

00:01:02,613 DEBUG [OgnlParametersProvider] Applying webSiteCategories[1] with [5]
00:01:02,615 DEBUG [OgnlFacade          ] cant find property for expression webSiteCategories[1] ignoring
00:01:02,615 DEBUG [OgnlParametersProvider] Applying webSiteCategories[14] with [13]

00:01:02,621 DEBUG [OgnlFacade          ] cant find property for expression webSiteCategories[0] ignoring

Foi mal. O problema foi que eu tinha renomeado o método e esqueci de renomear no jsp.
