Help with getExternalContext()

[basharf]

  Hello all,

I have this issue..

<h:commandLink name="Table Data" actionListener="#{tabTest.getValues}"  value="Table Data"/>

then I said to myself ..

I want to change it to a4j:commandLink...

so I put this...

<a4j:commandLink action="#{tabTest.getValues}" ajaxSingle="true" value="get results" reRender="taskList"/>

now in the bean ..

in the getValues method...

I have this   

UserBean userBean = (UserBean) FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("userBean");

it used to work when I used the <h:commandLink .. I can get the bean instance ...

but when I changed to the <a4j:commandLink ...

I cannot get the bean... it is NULL .. I dont know why .. weird...

can any 1 explain please ??

Please HELP

thanks

hi,

ajaxsingle maybe the problem.

Hi,

JSF beans are lazily evaluated, so evidently if you use ajax-single component userBean is not being called, thus it's missing in request. Why don't you inject it into tabTest instead of taking it from request map?

Thanks  a lot again..

1) remove ajaxSingle

or

2) inject using managed property instead of getting from request map.

hi,

can you switch your userbean to session scope?

[basharf]

hi,

this is injection with managed-property in your faces-config.xml

<managed-property>

<property-name>userBean</property-name>

<property-class>class.path.UserBean</property-class>

<value>#{userBean}</value>

</managed-property>
