how to call modal panel from managed bean

[jaabax]

hi
there is a way to call a modal from a managedbean?
i have seen some examples like this

//Class FacesHelper
 public static void addFatalMessage(String summary, String detail)
 {
 FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_FATAL, summary, detail));
 }

and inside managed bean I call it this way

FacesHelper.addFatalMessage("Smmay","Msg");

but when i call it, i received a "faces enqueued but maybe not displayed"
how to implement it
any tip?

You can use "oncomplete" event of a a4j components (like a4j:commandLink) to call Model Panel after doing something instead of your solution.

<a4j:commandButton value="button€"
oncomplete="javascript:Richfaces.showModalPanel('CustomPanel')"
action="#{someBean.someMethod}"
reRender="CustomPanel"/>

public class SomeBean
{
 private String fatalErrMsg = new String("Fatal Error!");

 public String getFatalErrMsg()
 {
 return fatalErrMsg;
 }
 public void someMethod()
 {
 //doing something with fatalErrMsg
 }
}

<rich:modalPanel>
 <h:outputText value="#{someBean.fatalErrMsg}"/>
</rich:modalPanel>
