Modal Panel hiding even when it contains the error messages

[prathap_dudvat]

I've a popup with requied field, a button with onclick and oncomplete events,

If there is validtion error occured like field required when clicked on a button,

it should show error is same popup,

but it is closing popup eventhough there is validtion error, as i have written oncomplete hide the modal panel

Please help me how to resolve this...

Is there any javascript way to find the error message in facescontext and then hide the modal panel based on the error message count in facescontext

[prathap_dudvat]

function checkmessagecount(){
var severityLevel;

// See if there are messages queued for the page
severityLevel = <%=FacesContext.getMaximumSeverity() %>

if (null != severityLevel) {


if (severityLevel.equals(<%= FacesMessage.SEVERITY_ERROR %>)) {
return true;
}
}
} 

will this work
