commandbutton inside panelgroup dont work

[javier pavon]

I have this code

<h:commandButton value="botonInside" action="protocolos"/>
<h:panelGroup rendered="#{historicoMedicacionManagedBean.listaMedPrescritos != null}">
         <h:commandButton value="botonOutside" action="protocolos"/>
</h:panelGroup>

I have two buttons, one inside of a panelgroup with a rendered condition and other outside.

When I open the page, two buttons are rendered because the condition is true, but when i click in the buttons, only the button "botonInside" works, the seconds button dont navigate and also will be disappear.

It is because, when i push the button "botonOutside", i dont know why but the panelgruop its rendered another time, before that navigation and then the condition its false.



Anybody know why after push the button the panelgroup it will be render another time? why the button "botonOutside" dont navigate???


Please, i need help.

Thanks

I am not sure I understood the problem... =P
Could you explain it step by step?

Do you use a4j or RichFaces in your aplication?

Hey.. remove the rendered attribute for the panel and try. If it works i'll tell you what the problem is and how to get over it.

What is the scope of your "historicoMedicacionManagedBean" ? Your button will not work if your managed bean's scope is request. You should save the state of the bean or the variable in the rendered attribute.

a lot of thanks for your replys!!!

The scope for the Bean it´s request, i cannot use session scope ;( and i need the rendered, because when the condition it´s false i dont want show the panelgroup.

I´m use richfaces, but in this example only i am using h:commanbutton.


The problem:
When i push the button "botonOutside", the panelgroup will be render another time, the condition will be false and the button will be dissapear and the aplicattion dont navigate. Why the panelgroup render when i push the button?

I need a button inside a panelgruop with a rendered condition for navigation.

Please, any help?

in reply to Akaine Harga, if i remove the rendered, the button works, but i need it ;(

Hi,
If you have Rich Faces , then use <c:if test="${urcondition}"><h:commandbutton></c:if>

We have certain issues in using panel Group.

Where is it this tag? jsf core? i dont found it

[Shan Narayanan]

c:if are jstl tags you can google it for reference.
They are work perfectly for conditional statements in jsp
