 System.out.println(paramVaule);- null



 But it returns null, what I'm missing?

I doubt it matters whether you are using tomahawk or richfaces or
something else.

Have you tried f:setPropertyActionListener target=#{VDBean.foo}
value=true / yet?

Yes but I don´t know if is the JSF version I'm using or something else
because I get a compilation error that says:

Error(461): f:setPropertyActionListener no es una etiqueta registrada en
ese espacio de nombres.

*In english: Error(461): f:setPropertyActionListener is not a registered
tag in that namespace*

Thanks

I also try:


1-
JSP:
h:commandButton value=seleccionar
actionListener=#{VDBean.seleccionar} id=seleccionarLink
   * f:param name=foo value=true/*
/h:commandButton

Please help! I only need to pass a parameter when a button is clicked to the
backingbean, but something so simple in teory is not working!

Re: a4j:support and a4j:actionparam

[Mike Kienenberger]

You need to put something similar to

xmlns:f=http://java.sun.com/jsf/core;

at the top of your template file.

I don't remember the exact syntax for that under jsp -- I use facelets
for everything.

However, I would think you would get the same error for f:param and f:attribute.

Thanks mike, I already have it: %@ taglib uri=http://java.sun.com/jsf/core;
prefix=f% in fact I use other tags with the f: prefix, but
f:setPropertyActionListener do not appears.

Re: a4j:support and a4j:actionparam

[Mike Kienenberger]

I have not used a4j:actionparam, but under richfaces, I have successfully used

a4j:support
 f:setPropertyActionListener target=#{target1} value=#{value1} /
 f:setPropertyActionListener target=#{target2} value=#{value2} /
/a4j:support

Perhaps that will do what you need.

 when access the foo variable in the VDBean (scope: session) select method it

 Can anyone help me?

 Thanks

Thanks Myke but I'm using myfaces tomahawk, not richfaces.

I also tried a more simple code:

In the JSP:

h:commandButton value=seleccionar
actionListener=#{VisitaDomiciliarBean.seleccionar} id=seleccionarLink

/h:commandButton

FacesContext context = FacesContext.getCurrentInstance();

System.out.println(paramVaule);- null
