Rene O commented on MYFACES-3881:
---------------------------------
I have found a workaround for my current usecase:
My idea is similar to client mode (javax.faces.CLIENT_WINDOW_MODE -> client),
but doesn't use requestparam 'mfRid'.
Implementation:
- using of deltaspikes @WindowScoped for my beans (@ViewScoped doesn't work
here)
- using of special viewAction
{code:title=web.xml}
<context-param>
<param-name>javax.faces.CLIENT_WINDOW_MODE</param-name>
<param-value>url</param-value>
</context-param>
{code}
{code:title=mypage.xhtml}
<f:metadata>
<f:viewAction action="#{initCtr.initApplication()}"/>
</f:metadata>
{code}
{code:title=InitCtr.java}
public void initApplication(){
FacesContext ctx = FacesContext.getCurrentInstance();
ExternalContext exCtx = ctx.getExternalContext();
String windowid = exCtx.getClientWindow().getId();
System.out.println("windowid: "+windowid);
//get current requestparams
Map<String,String> reqparams = exCtx.getRequestParameterMap();
//only redirect if no jfwid exists yet or an old unknown jfwid
is used within the browser
if(!reqparams.containsKey("jfwid") ||
!windowid.equals(reqparams.get("jfwid"))){
try {
StringBuilder sb = new StringBuilder();
sb.append("?");
//append all requestparams
for (Map.Entry<String,String> entry :
reqparams.entrySet()) {
sb.append(entry.getKey()).append("=").append(entry.getValue()).append("&");
}
//append jfwid to be able to decide if a new
'windowsession' is needed or not
sb.append("jfwid=").append(exCtx.getClientWindow().getId());
//redirect to same page with new added jfwid
param
exCtx.redirect(exCtx.getRequestContextPath()+exCtx.getRequestServletPath()+sb.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
{code}
A new showcase (jsftest22_new.zip) is attached:
http://localhost:8080/jsftest22/mypage.jsf
> CLIENT_WINDOW_MODE generates new windowid even if one exists

> Key: MYFACES-3881
> URL: https://issues.apache.org/jira/browse/MYFACES-3881
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.2.2
> Environment: java 7, tomcat 7.0.50
> Reporter: Rene O
> Attachments: jsftest22.zip, jsftest22_new.zip
>
>
> If you use @ViewScoped beans and activate CLIENT_WINDOW_MODE (url or client)
> a page refresh generates a new windowid although the application in the
> current browser window already has a windowid.
> I think a new windowid should only be generated, if no windowid exists, e.g.
> open new window or tab with the same url.
> <context-param>
> <param-name>javax.faces.CLIENT_WINDOW_MODE</param-name>
> <param-value>url</param-value>
> <!--client doesn't work too-->
> </context-param>
> A testcase is attached.
> call url: http://localhost:8080/jsftest22/mypage.jsf
> Fill some values into field
> Press F5 to refresh the page
> => new windowid is generated => inputdata is lost, because a new @ViewScoped
> bean was created
