Werner Punz commented on MYFACES-2876:
--------------------------------------

Next issue, following construct makes the winmobile browser fail

onclick="javax.faces.request(this, event, ....)"

the issue here is that ie does not pass an event object but instead relies in 
window event, to make the code work the follwing code has to be passe ddown
onclick="javax.faces.request(this, ('undefined' == typeof event)? window.event: 
event, ....)"

We probably have to fix that on the f:ajax level in the long run for now it is 
not that important.

>             Project: MyFaces Core
>          Issue Type: Bug
>          Components: General
>    Affects Versions: 2.0.0-beta
>         Environment: Windows Mobile 6.1, Blackberry 4.7
>            Reporter: Mamallan Uthaman

> In Windows Mobile (WM) 6.1 platform, <f:ajax> is converted into a full-page 
> submit instead of a PPR. The reason is unlike Webkit based mobile-browsers, 
> WM 6.1 or Blackberry (BB) 4.7 offers only a limited JavaScript-DOM support, 
> so we need to optimize MyFaces's Ajax mechanism to work around the 
> limitations of mobile browsers. I used the sample code below for testing.
> Facelets code:
> <h:commandButton value="PPR">
>   <f:ajax event="action" render="second"/>
> </h:commandButton>
> <h:outputText value="#{item.date.seconds}" id="second"/>
> Item.Java:
> import java.util.Date;
> public class Item {
>   Date date;
>   public void setDate(Date date) {
>     this.date = date;
>   }
>   public Date getDate() {
>     return new Date();
>   }
> }
> faces-config:
> <managed-bean>
>   <managed-bean-name>item</managed-bean-name>
>   <managed-bean-class>Item</managed-bean-class>
>   <managed-bean-scope>request</managed-bean-scope>
> </managed-bean>
> Also, in the case of  BB 4.7 , <f:ajax> can successfully send a PPR, but PPR 
> response is ignored.
