Request error, status 500: Internal Server Error Message:null
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

Hi,
Yes you are right. I am getting FacesContext.getCurrentInstance()as null.
Why this is null. I am not able to find out why it becomes null. If you have any idea please
let me know.
Thanks & Regards,
Basha,

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,
If I want to pass the parameter to a backing bean method through <a4j:commandLink>,
without using <a4j:actionParm> is there any another way to do it? If any please let me know.
Due to this error my application is crashing.
Thanks & Regards,
Basha,

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.
Regards,
Basha

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']

Check everything in you user session is serializable. During application
reload, the container serializes user sessions and deserialize them
after reload. It maybe that one of you backing beans had serialization
problems and did not get properly restored (transient fields?)
