Problems with modal Panel

[lgweb]

How to close a modal if there is no error messages on inside it? Because I have a screen that has multiple applications only when I ModalPanel the display, and has error messages on the hour to save it closes anyway, see my code :

 <rich:modalPanel id="loadCliente" autosized="true" top="10" left="100">
 <f:facet name="header">
 <h:outputLabel value="#{msg.cadastrarcliente}"/>
 </f:facet>
 <f:facet name="controls">
 <h:graphicImage value="/images/BOTOES/cancel.png" width="20" height="20"styleClass="imagem"
 style="cursor:pointer" onclick="Richfaces.hideModalPanel('loadCliente')" />
 </f:facet>
 <center>
 <c:import url="/view/cliente/modal.jsp"></c:import>
 </center>
</rich:modalPanel>




<a4j:region renderRegionOnly="true">
<rich:modalPanel id="loadForma" autosized="true" >
 <f:facet name="header">
 <h:outputLabel value="#{msg.produto}"/>
 </f:facet>
 <f:facet name="controls">
 <h:graphicImage value="/images/BOTOES/cancel.png" width="20" height="20"styleClass="imagem"
 style="cursor:pointer" onclick="Richfaces.hideModalPanel('loadProduto')" />
 </f:facet>
 <center>
 <c:import url="/view/forma/modal.jsp"></c:import>
 </center>
</rich:modalPanel>
</a4j:region>

<script type="text/javascript">
 function windowcloseCliente(){
 if (document.getElementById('erroCliente')==null){
 javascript:Richfaces.hideModalPanel('loadCliente');
 };

 };

 function windowcloseForma(){
 if (document.getElementById('formaModal:erroForma')==null){
 javascript:Richfaces.hideModalPanel('loadForma');
 };

 };


 function windowcloseCidade(){
 if (document.getElementById('erroCidade')==null){
 javascript:Richfaces.hideModalPanel('loadCidade');
 };

 };

 function windowcloseEstado(){
 if (document.getElementById('erroEstado')==null){
 javascript:Richfaces.hideModalPanel('loadEstado');
 };

 };

This is a ModalPanel for display messages from home:

<rich:modalPanel id="error" autosized="true"
 showWhenRendered="#{facesContext.maximumSeverity !=null}">
 <f:facet name="header">
 <h:outputText value="#{msg.erros}"></h:outputText>
 </f:facet>
 <f:facet name="controls">
 <h:graphicImage value="/images/BOTOES/cancel.png" width="20"
 height="20" styleClass="imagem" style="cursor:pointer"
 onclick="Richfaces.hideModalPanel('error')" />
 </f:facet>
 <table class="blank" style="font-size: 10pt; white-space: nowrap">
 <nobr> <rich:messages showDetail="true" showSummary="true">
 <f:facet name="errorMarker">
 <h:graphicImage value="/images/requirid.png" width="20" height="20"
 styleClass="imagem" />
 </f:facet>
 <f:facet name="warnMarker">
 <h:graphicImage value="/images/info.png" width="20" height="20"
 styleClass="imagem" />
 </f:facet>
 <f:facet name="infoMarker">
 <h:graphicImage value="/images/accept.png" width="20" height="20"
 styleClass="imagem" />
 </f:facet>
 </rich:messages> </nobr>
 </table>
 </rich:modalPanel>

The modal panel displays messages but closed soon after, as I do not close it?
