Hi, Matthias

You may using next code

<h:form>

         <rich:popupPanel id="popup" domElementAttachment="form" modal="true"

                          onmaskclick="#{rich:component('popup')}.hide()"

                          resizeable="true">

             <f:facet name="header">

                 <h:outputText value="header"/>

                 <f:facet name="controls">

                     <h:outputLink value="#"

                                   onclick="#{rich:component('popup')}.hide(); return false;">

                         X

                     </h:outputLink>

                 </f:facet>

             </f:facet>

            <br/><br/>

              <h:outputText value="You question ..."/>

             <br/><br/>

            <h:panelGrid columns="2">

                <a4j:commandButton

                         actionListener="#{myBeen.doSomething}"

                         onclick="#{rich:component('popup')}.hide(); return true;"

                         value="OK"/>

                <h:commandButton

                         onclick="#{rich:component('popup')}.hide(); return false;"

Hello Vitaliy,

thanks for the fast answer.

How can i make the Popup open out of a java method ?

YOu can't. You must write your controller (JSF backing bean) the right way.

i.e.

{code:java}public class Bean {
    private Object attributeA;
    //getters and setters
    public String doStuff() {
        if(this.attributeA==null) {
            return "dataNeeded";
        }
        //...other checks
        //final logic
    }
}{code:java}

{code:xml}<rich:popupPanel id="popup" .../>
<a4j:outputPanel ajaxRendered="true">
    <h:panelGroup  rendered="#{empty bean.attributeA}">/**JavaScript showing panel*/</h:panelGroup>
</a4j:outputPanel>{code:xml}

hmm ok

Thats my code at the moment:

<a4j:outputPanel ajaxRendered="true" >

<h:panelGroup  rendered="#{myController.showit}">

            //Need a way to execute Javascript..

</h:panelGroup>

</a4j:outputPanel>

            <rich:popupPanel id="popup" modal="true" resizeable="true"   >

            <f:facet name="controls">

                <h:outputLink onclick="#{rich:component('popup')}.hide()">X</h:outputLink>

            </f:facet>

               TEXTEXTTEXTTEXTEXTTEXTTEXTEXTTEXT<br/>

               TEXTEXTTEXTTEXTEXTTEXTTEXTEXTTEXT ?

                <h:panelGrid columns="2">

                    <a4j:commandButton value="Ja" onclick="#{rich:component('popup')}.hide()">

                        <a4j:ajax event="click" listener="#{myController.doSthForYes()}"/>

                    </a4j:commandButton>

                    <a4j:commandButton value="Nein" onclick="#{rich:component('popup')}.hide()" >

                        <a4j:ajax event="click" listener="#{myController.doSthForNo()}"/>

                    </a4j:commandButton>

                </h:panelGrid>

            </rich:popupPanel>

How can i execute Javascript ?

is there an onrendered, that i can #{rich:component('popup')}.show() or what is the way of showing the panel  ?

in the methods doSthForNo and doSthForYes i can place my logic ? and in the end set the showit to false that no more popups will come out ?

substitute "//Need a way to execute Javascript.."

with

<script>#{rich:component('popup')}.show();</script>

Yes, doSthForNo and doSthForYes are the right place for logic, and yes, change value of showit to false if you don't want to show the modal panel.
