If you mean that jbpm stuff, the implementation of this method is:
public static String getParameter(String name) {
return
(String)FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get(name);
}
So either with your FacesContext is something wrong or your
buttonClicked just becomes null, and the exception is thrown later (i.e.
while accessing buttonClicked as String). If so, it may be the same
issue that I've discovered with <a4j:actionParam> but unfortunately I
can't yet figure it out precisely. In my application <a4j:actionParam>
'less' the value, if it's inside some container with rendered=false.
Your issue seems to be very similar. If nothing helps, I'd try to ask
this in a4j support forum.

Hi,
No I am getting the resource bundles messages fine only. Only
the problem is
When I am clicking on the command link it is calling the bean method.
Inside the bean method I am getting the parameter which I sent using
<a4j:actionParam> tag as follows,
String buttonClicked = JsfHelper.getParameter("buttonName");
Then here I am getting null pointer.

Hi Basha,
it sounds like some session expiration issue. Aren't you getting the
same exception after restart of JVM? If so, the issue can be also your
resource bundle msg['historyView.leftArrowImage']

Hi,
In my web application I am using MyFaces, a4j tags and JBoss server.
When I am starting my server for the first time my application is
running fine.
After that if I redeploy my application without restarting my server
then I am getting
"*Request error, status 500: Internal Server Error Message: null" *if
I click on the <a4j:comandLink>
But I am passing one parameter to the backing bean through
<a4j:actionParam> tag.
My code is like as follows,
<a4j:commandLink id="leftScrollBarButton"
action="#{customerBean.regenerateHistoryView}" >
<img border="0" src="images/bluearrowleft.gif"
title="#{msg['historyView.forward']}"
alt="#{msg['historyView.leftArrowImage']}"></img>
<a4j:actionparam id="buttonName" name="buttonName"
value="button_left"/>
</a4j:commandLink>
Moreover in my server logs I am getting "Null Pointer exception". Can
any body have any idea?
Thanks & Regards,
Basha
