Dynamic simple content inside modal panel

[leiras]

Hi,

i'm trying to put a simple HtmlOutputText dynamically inside a modal panel. Please take a look at my code:

JSP:

<rich:modalPanel id="mpProtocoloSanitario" autosized="true" >
<h:form>
<rich:panel style="height: 30px; width: 200px; background-color: #0000FF;" >
<h:outputText value="Test"/>
</rich:panel>

<rich:panel id="pnProtocoloSanitario" binding="#{rastreador.panelProtocoloSanitario}" />

<rich:panel style="text-align:center;margin-left: auto;margin-right: auto; margin-top: auto; margin-bottom: auto; border-width: 0px 0px 0px 0px; height: 30px;background-color: transparent;" >
<h:graphicImage url="/imagens/bt_fechar.png" style="cursor: hand; cursor: pointer; margin-top: 10px;" onclick="javascript:Richfaces.hideModalPanel('mpProtocoloSanitario')" />
</rich:panel>
</h:form>
</rich:modalPanel>

JAVA:

private void updatePanel(HtmlPanel panel) {
 if (panel == null) {
 panel = new HtmlPanel();
 } else {
 panel.getChildren().clear();
 }

 HtmlOutputText ot = new HtmlOutputText();
 ot.setRendered(true);
 ot.setId("otTest");
 ot.setValue("Test Modal Panel");

 panel.getChildren().add(ot);
}

The method "updatePanel" is called after a click on a button.
I have an attribute private HtmlPanel panelProtocoloSanitario; at my bean, with get and set.
The modal panel opens, but the "HtmlOutputText ot" is not displayed. What i am doing wrong? Thanks for the help.
