JSF & RichFaces – how to display Rich:toolTip for a disabled h:commandButton ?

Posted on by

We want to display information overview of a h:commandButton. This information is different if the button is disabled or not.

Problem

If the h:commandButton is disabled, the rich:toolTip doesn’t appear.

 
<h:commandButton id="myButton" value="Action" action="#{myBean.myFunction()}" disabled="#{myBean.myVariable}" >
	<rich:toolTip for="myButton" followMouse="true" styleClass="tooltip" showDelay="300" > 
	         <h:outputText value="my message if the button is not disabled" rendered="#{myBean.myVariable==false}"/>
                 <h:outputText value="my message if the button is not disabled" rendered="#{myBean.myVariable==true}"/>
	</rich:toolTip>
</h:commandButton>

Solution

 
<a4j:outputPanel>
	<h:panelGrid columns="1">
		<h:commandButton id="myButton" onmouseover="#{rich:component('infoBtn')}.show()" onmouseout="#{rich:component('infoBtn')}.hide()" value="Action" disabled="#{myBean.myVariable}" action="#{myBean.myFunction()}" />
	</h:panelGrid>
	<rich:toolTip id="infoBtn" >
		<h:outputText value="my message if the button is not disabled" rendered="#{myBean.myVariable==false}"/>
												<h:outputText value="my message if the button is not disabled" rendered="#{myBean.myVariable==true}"/>
	</rich:toolTip>
</a4j:outputPanel>

Seam – <action execute="…"> in Pages.xml run with JSF Ajax component

...
<h:panelGrid id="panelMyButton">
      <a4j:commandButton value="myButton" action="#{myBean.execute()}" reRender="panelMyButton" ajaxSingle="true" />
</h:panelGrid>
...

@Name("myBean")
@Scope(ScopeType.SESSION)
@Synchronized(timeout=99999999)
public class EditReclamationAction implements Serializable{   
    ...
    public void init(){
       ...
    }
    public void execute(){

    }
    ...
}

<page view-id="myView.xhtml">
    ...
    <action execute="#{myBean.init()}" />
</page>

Problem

Even if the action in <a4j:commandButton> is in ajax, the tag in pages.xml run the function init(). That’s how work in Seam.

Solution

Change the way to execute function and the scope type of the bean.

  • In the bean, modify @Scope(ScopeType.SESSION) by @Scope(ScopeType.PAGE) to let possibility to initialize for each page loading
  • In the bean, add “@Create” upper init(), that means for Seam run this function for each page loading
  • Delete the tag <action> in pages.xml

like this :

 
...
<h:panelGrid id="panelMyButton">
      <a4j:commandButton value="myButton" action="#{myBean.execute()}" reRender="panelMyButton" ajaxSingle="true" />
</h:panelGrid>
...

@Name("myBean")
@Scope(ScopeType.PAGE)
@Synchronized(timeout=99999999)
public class EditReclamationAction implements Serializable{   
    ...
    @Create
    public void init(){
       ...
    }
    public void execute(){

    }
    ...
}

<page view-id="myView.xhtml">
    ...

</page>
