Erro no JSF - não encontra método

Tenho o seguinte trecho em uma página jsp

<h:outputLabel value="Descrição:"/>
            <h:panelGroup>
                <h:inputText id="descricao" size="40" maxlength="150" value="#{cadastroContaBean.contaEdicao.descricao }" label="Descrição" required="true"></h:inputText>
                <rich:suggestionbox for="descricao" suggestionAction="#{cadastroContaBean.sugerirDescricao }" width="230" height="120" var="item">
                    <h:column>
                        <h:outputText value="#{item }"/>
                    </h:column>
                </rich:suggestionbox>
                <h:message for="descricao" showSummary="true" showDetail="false" styleClass="msgErro"></h:message>
            </h:panelGroup>

Quando o métdo sugerirDescricao da managed bean CadastroContaBean é chamado aparece o seguinte erro

GRAVE: Servlet.service() for servlet [Faces Servlet] in context with path [/Financeiro] threw exception [/contas/cadastroConta.jsp(49,4) ‘#{cadastroContaBean.sugerirDescricao }’ Method not found: [email removido](java.lang.Object)] with root cause
org.apache.jasper.el.JspMethodNotFoundException: /contas/cadastroConta.jsp(49,4) ‘#{cadastroContaBean.sugerirDescricao }’ Method not found: [email removido](java.lang.Object)

Ou seja, diz que meu método não foi encontrado, porém ele está lá. Vou mostrar meus códigos completos:
