How to call popup based on a condition in richfaces? - jsf

Question

I am trying to understand popup menu in richfaces. I am trying to do the following: I have a textbox and a button. I write some text into the textbox, and if the value of the text written is "popup", i want to call the popup menu. Here is the code:
<h:form>
<h:inputText value="#{popupCall.text}"></h:inputText>
<a4j:commandButton action="#{popupCall.showpopup()}" onclick="if (#{popupCall.showpopup()}) #{rich:component('popup')}.show();">
</a4j:commandButton>
</h:form>
<rich:popupPanel id="popup" modal="false" autosized="true" resizeable="false">
<f:facet name="header">
<h:outputText value="Popup panel" />
</f:facet>
<f:facet name="controls">
<h:outputLink value="#" onclick="#{rich:component('popup')}.hide();
return false;">
X
</h:outputLink>
</f:facet>
</rich:popupPanel>
and the bean:
#ManagedBean (name="popupCall")
#VievScoped
public class PopupCall {
private String text;
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public PopupCall() {
}
public void checkText(){
if(text.equals("popup")){
//CALL POPUP MENU
}
}
public boolean showpopup(){
if(text!=null && text.equals("popup"))
return true;
else
return false;
}
}
If i don't put "if(#{popupCall.showpopup()})" inside the onclick method it always calls when button is pressed but now even though the showpopup()method returns true no popup is shown. Also, inside the showpopup() method, if i just write return true, the if statement inside onclick works but now it does not.
Can anyone help me with this? Thanks

For your case you want to use oncomplete instead of onclick since you want to show <rich:popupPanel> after executing some business logic. When I changed
onclick="if (#{popupCall.showpopup()}) #{rich:component('popup')}.show();"
to
oncomplete="if (#{popupCall.showpopup()}) #{rich:component('popup')}.show();"
The pop up showed up. Also be careful with
action="#{popupCall.showpopup()}"
Remember that action needs String (or null) for navigation but
showpopup() is returning a boolean so you might want to fix that.
